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.
Staying Computer Safe while Searching for Freebies on the Net Who doesn’t love the idea of getting something for nothing? Free stuff can bring a smile to anyone’s face, and the Internet is destination number one when you are looking for cash in on a few freebies. The downside of free stuff online is that if you aren’t careful, the free item could end up causing plenty of headaches and heartaches, not to mention a lot of cold, hard cash. If you want to score with free stuff online, make safety your number one priority by following these tips. First and foremost, treat your personal information like its cash. That might sound a little dramatic, but anyone who manages to steal your identity online is after one thing, and one thing only, your money and any addition money they can grab by cashing in on your credit. Protecting your name, address, credit card number, bank account number, phone number, social security number, and so on and so forth when you are registering for free offers is the first step to making sure you don’t get hustled when you’re just trying to enjoy a good freebie. That means that if you are asked for some personal information that you don’t feel comfortable handing out, let the freebie go. Likewise, make sure the site from which you are getting your free stuff has a privacy policy and that you know it, understand it, and can live with it. Speaking of that site that is handing out the free goods: just who are these people? If you were walking down the street and a shady looking person said they would give you a free DVD player if you followed them, chances are you would run the other way. Online, it is hard to tell the legitimate people from the people looking at you like a free lunch, but there are a few red flags you can look out for. Does the website look like it was thrown up in about 5 minutes, full of clip art and bad spelling? Is it hard to find information about where the website is registered, or where the business the website is supposedly promoting is registered? If the website purports to be affiliated with a certain brand you know, does it really look like it is, or does the logo look different/colors look off? If you can’t get a reasonable feel for who are dealing with online, don’t deal with them. Red flag number one? Asking for too much personal info should send you running. Another way to protect yourself is to build a virtual fortress around your computer. The net is filled with people who know how to walk right into your virtual home – your computer – and flip through everything you have on there, taking whatever they want. Many of these kinds of hackers draw you in by creating phony freebie websites. The way to keep them out is to keep your computer on lockdown. Make sure your firewall is stronger than you think it needs to be, and make sure it is always updated. Also, make sure you have antivirus software on the patrol for you and that you keep this software updated as well. Last but not least, keep those passwords in the vault, and make sure they are extra strong. No freebie website has any reason to ask you about the passwords for your accounts so don’t give them away – and don’t give them to anyone else online for that matter. Also, if you’re using your birthday or child’s name as password, don’t. Sure, it isn’t as easy to remember, but your password should be a random word and contain a collection of numbers and symbols as well. This will give you the extra layer of protection to make sure your online house is in order when you cash in on the freebies. Software Copyright Laws Software Copyright Laws Fail to Provide Adequate Protection Software copyright laws are among the most difficult to enforce among the masses. Many companies and corporations are also well known for overlooking these laws, which were designed to protect the makes of software from not earning their worth. Perhaps one of the biggest hitches leading so many software businesses to go out of business is the fact that they have a great deal of difficulty actually enforcing the software copyright laws that are in place and getting the money that is owed them according to the agreements that have been made with those on the using end of the software. Software developers, particularly in the corporate world design software that makes other companies run more efficiently. The software allows these companies to save millions of dollars each year. Software copyright laws protect the interests of the software developers that create these massive programs. These programs are often designed specifically for that one company and are very expensive. The agreement often consists of a certain number of users with the company purchasing more licenses or copies of the software during expansions or paying some sort of royalties for the use of the software. The purchasing companies agree to this and then more often than not fail to honor that agreement. The agreement is what allows this company to use that software, this agreement is what allows that permission. When companies aren't living up to their end of this agreement they are not only guilty of breaching that agreement but also of breaking software copyright laws. The trouble always lies in proving that they are not honoring the contract and the extent and duration of the breach. Some of the ways that companies will argue in defense of them not paying the royalties, additional fees, purchasing additional software, etc. is that they upgraded computers and reused the old software (they did actually purchase the rights to use the original software and by doing so feel that they have broken no software copyright laws) the problem lies in the fact that adding ten new computers and placing the software on those should mean that you remove it from or get rid of 10 old computers. This is rarely how it works. So now they've basically stolen ten copies of software that can be well worth hundreds of thousands of dollars. Multiply this by 10, 20, or 100 companies trying this or worse each year and the offending companies are costing software developers millions of dollars in profits. This is when software copyright laws are not as far reaching in their scope as they really need to be. Software copyright laws exist to protect the software companies from this type of abuse and misuse, however, the hands of the companies are almost unilaterally tied when it comes to proving that software copyright laws have been broken in court. There are always exceptions to every rule. In this case big business software developers that abuse the software copyright laws to the point of breaking make the exceptions rather than miserly consumers that do not wish to pay for the products they are consuming. The big boys are able to do this by offering licenses for their software and claiming that these laws do not apply to their situation because they are not actually selling the software only 'renting' out permission for people or companies to 'use' that software. The true irony is that these practices began as a response to the corporate irresponsibility mentioned above. It's amazing that the very software copyright laws that were created to protect these companies can't protect their consumers from the greed of the developing companies. |
