Web Hosting - Domain Name Changes and How They Affect You
New domain names are registered all the time, and ones previously registered expired. Sometimes that's the result of simple neglect. The owner of the name chose not to renew his or her ownership, so the name became available for someone else to use. In rare cases, a highly original mind managed to think of a new one. In the other common scenarios, someone chose to just let it go or sell it.
When you choose to change your domain name, there are actually two separate steps involved: releasing the old name, and adopting the new one. But, just as the postal system can have difficulty forwarding your letters when you change your personal name, changing your domain name brings certain difficulties.
One of the most prominent is the fact that any name change requires a change to thousands of DNS Servers around the globe. DNS (Domain Name System) is the set of software/hardware components that allows domain names to map to IP addresses. IP addresses are what are actually used 'under the covers' when one computer communicates with another.
Note that there isn't always a 1:1 correspondence between a name and an IP address. One IP address can serve multiple domain names and one domain name can have multiple IP addresses. For the sake of simplicity, we'll stick to the common case here.
DNS servers around the world maintain internal databases that match the name to an IP address. Not all servers have all pairs of names/addresses. A series of complex routines allows a request to be forwarded when the particular DNS server doesn't have a needed record. When you acquire a domain name that used to be associated with a given IP address, the odds of you acquiring the same IP address are extremely low.
In the unlikely case, for example, that you acquired the domain name yahoo.com, you would almost certainly not get the IP address that was matched with it (unless you bought the Yahoo! company). So, as a result of the change, the name/IP address pair is no longer what it was.
A similar circumstance exists when you retain your IP address, but want to change the domain name associated with it. In either case, the pairing has changed.
The catch is this: when the change takes place, those DNS databases are not all updated instantaneously around the world.
Even apart from the limited speed with which computers and networks operate, (and neglecting the human factor if/when the change is made manually to more than one server) the reason is something called caching.
In order to communicate efficiently, DNS servers are designed to assume that changes will be relatively rare. Just as with the postal system, you don't move your address or change your name every minute. Since that's true, in general, the name/IP address pair is cached. A cache is a set of stored information that is reused so that fresh information doesn't have to be communicated with every request for a web page or data.
A chain of DNS servers pass requests to the last known address. There is usually more than one system between your computer and the server you want to communicate with. Most of the time, that's your current name/address. When you change the name, that pair is no longer valid. In order to propagate the new name/address pair (so the terminology goes), that cache has to be refreshed.
Something similar happens when you establish an entirely new name. That name is first associated with an IP address and that pair has to be communicated to DNS servers around the world in order for you to be able to reach any one of them at random.
But DNS servers don't do that until they are requested to do so by your action of asking for information from a remote server. Because of that, but chiefly because of caching, it can take quite a while for the new pair to become known around the Internet. Caches can expire and get refreshed in a few minutes or a few hours. It varies.
That time can be as short as an hour or less, if the path between your computer and the web server is very simple and only one DNS server needs to be updated. Or, it can take up to 48 hours or more. Though the 'official' range is often given by registrars as 24-48 hours, the average is closer to about six hours. But that's an average. The actual time in any given case can (and does) vary widely.
In the meantime, a number of effects can occur. The most obvious is that, since the name/IP address pair can't be resolved properly, you don't reach the server you want. Your browser points to the old one (in the rare case it's still accessible by that name and address), or it simply reports there's no such name at that address.
So, when registering a new name or buying an old one, you should establish the site, but not advertise it for at least a couple of days. Better to wait to get visitors than to turn them off by being 'not at home' when they call.
Web Hosting - Why Backups Are Essential One thing most web site owners have little time for is... anything! Anything other than focusing on their site content and the business or service it supports and the information it provides, that is. That means that administration often suffers, as it frequently must. There's only so much time in the day. But the one thing that you should never let slide are backups. They are like insurance. You rarely need it (you hope), but when you do you need it very badly. Performing regular backups - and testing them - doesn't have to be a nightmare. A little bit of forethought and effort and they can be automated to a high degree. And, they should be tested from time to time. Even when a backup appears to have gone without a hitch, the only way to know whether it's of any value is to attempt to restore the information. If it can't be restored, the backup is worthless. Even when the web hosting company provides the service, there is still some planning involved for the site owner. Hosting companies often rely on one or both of two methods. They backup everything (called a full backup), then backup anything which has changed since the last full backup (called an incremental backup). Of special interest are any configuration files that have been tailored. If you've modified the default installation of a software package, you want to be able to recapture or reproduce those changes without starting from scratch. Network configuration files, modifications to basic HTML files, CSS style sheets and others fall into the same category. If you have XML files, databases, spreadsheets or other files that carry product or subscriber information - about items purchased, for example, or people who signed up for a newsletter - those should get special attention, too. That's the lifeblood of your business or service. Lose them and you must start over. That can break your site permanently. It should go without saying that all HTML and related web site files that comprise visible pages should be backed up regularly. It isn't necessary to record every trivial change, but you can tailor backup software to exclude files or folders. Usually they're so small it isn't worth the trouble. But in some cases those small changes can add up in scenarios where there are many thousands of them. Here again, the backups are worthless if they can't be used. Even if the hosting company charges for doing so, it's worthwhile to test once or twice a year at least to ensure the data can be restored. That's especially true of database backups, which often involve special software and routines. Database files have a special structure and the information is related in certain ways that require backups be done differently. Developing a backup strategy can be straightforward. Start simply and review your plan from time to time, modifying it as your site changes and grows. But don't neglect the subject entirely. The day will come when a hard drive fails, or you get hacked or attacked by a virus, or you accidentally delete something important. When that day comes, the few minutes or hours you spent developing and executing a backup plan will have saved you days or weeks of effort.
How to copyright music How to Copyright Music for the Beginner For those wondering how to copyright music the answer can be both long and short. The first thing to remember is that most people are confused about exactly what it means to actually copyright music. Music is actually copyrighted as soon as it is presented in a fixed form. It doesn't really matter whether that fixed form is as written sheet music or as a recording. Most people are looking for solid legal protection and while a copyright is good to have, it is essentially worthless unless you've actually gone to the effort of also registering your copyright. Rather than asking 'how to copyright music', perhaps the better question would be 'what do I do now that I've copyrighted my music?' It doesn't really matter what you call it unless you're moving around in legal or industry circles I suppose, but I've always felt that it's a good idea to have a clue about the process in which you are embarking. Now that we've answered how to copyright music, it's time to move on to the real issue, which is registering your copyright. Music is registered through the U. S. Copyright Office. You will need to fill out an application, pay a fee, and provide a copy of your music. As far as government dealings go, this is one of the least painful. Even the fee is marginal when you consider your 'hopeful' future profits and royalties. All that aside, there is something that is massively satisfying about knowing how to copyright music and having your first piece of music registered. Music is an art form and the ability to write music is nothing insignificant. It is a real talent that is actually quite rare. Many popular musicians today use music that has been written by others either in addition to or rather than music that they have written themselves. Even if you aren't a talented performer, it doesn't mean that your music will never be seen or heard or that you should not bother learning how to copyright music. You just might find that you are more in demand for your particular talents than you would have ever dreamed possible. The big thing to remember though is not to sit around wondering how to copyright music but to get out there and go about the process of creating and making more wonderful music to share with the world. It takes all kinds of music to keep this world turning and there is someone out there that is waiting to hear the music that you create. The process of how to copyright music is completely free. The process of registering your copyright is worth every penny you will spend. It is important to protect your music now more than ever with piracy and widespread downloading providing significant reductions in profits for everyone involved. The music industry is also a very fickle industry and you need to maximize your profit potential and usefulness. Once you understand how to copyright music, you need to make sure every piece of music you have has been copyrighted, then you need to go through your music and systematically register each and every piece as well. Even if you must do one piece at a time until you manage to register the copyright on them all, it is much better to be safe than sorry should you ever go to trial in a copyright infringement case. Also remember to pay it forward and support up and coming musicians by sharing the information of how to copyright music and how to register copyrights as well.
Understand Group Publishing (group publishing) When you want to have one your books published, you will work hard to get your book finished and then you will seek out a publisher. Sometimes it is very hard to find the right publisher, but the good news is that there are several different types of publishers that you can use to get your works on the market. Large companies are not your only option. The world of publishing difficult to break into and if you get an acceptance letter--that is only the start. There are many types of publishing companies out there and they all have a different way of publishing their products. Here is a look at some of the more common types of publishing including group publishing. Group Publishing: Group publishing is the process in which a large company publishes your work in the name of a larger company. For example, there are big name publishing companies out there. They operate smaller group publishing companies. The larger publishing company serves as a kind of umbrella over the smaller group publishing companies. Sometimes these companies operate several smaller companies that produce different genres of writing and books. This is also sometimes called trade publishing. For example, a large publishing group may produce best selling adult novels, but may also operate under a smaller name to produce certain non-fiction books, cookbooks or children?s books. Group publishing is a popular way to publish a book. Educational Publishing: Besides trade publishing, there is also educational publishing. These are companies that deal specifically with educational material. They may deal with only college textbooks, or they might deal with textbooks and materials for grades K-12. Besides textbooks, these companies might also produce other forms of educational material, which include posters, workbooks, CD-ROMS, software, testing material and maps. There are several big name educational publishing companies. University publishing?University Press: This type of publishing is not like group publishing and it is not the same as scholarly publishing. These types of companies are usually non-profit and are run by universities, colleges and even sometimes museums or other organization. These usually publish books by scholars and other specialists and they usually are used within the university system. Sometimes these books do get published by a larger trade publish; however, they do not market these types of books. Independent publisher: Independent publishers are often the best way to get your book published if you cannot find a publisher to produce your book. These are generally smaller companies that are privately owned. Many times, these companies only publish a handful of books each year and they usually are about certain subjects. They have the freedom to publish just about anything they wish. Software and other Media: You might not consider software and other types of media as being a publisher, but they are. Think of all the e-books, CD-ROMs and even books on tape that are on the market. These have to be published, too. These types of companies are often associated with larger trade publishers. In fact, many large publishing companies have their very own media publisher in house to take care of this type of publishing. It is a very large business and these types of publishers are just as important and lucrative as the large trade publishers. As you can see, there is a whole world of publishers out there waiting to get your book or other media published. If you do not have luck with a large trade publisher or group publisher, then don?t give up. Keep looking and the different types of companies out there until you find one that wants to work with you and your book.
