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.
Software copyright buy For Software Copyright Buy Locally To gain permission to use software copyright, buy the software. This sounds like such a simple solution and yet I know this isn't always as easy as it seems. Software is expensive, largely due to misuse and abuses of the past and the average consumer can't always afford to buy the software package and product he or she needs for business or pleasure. It is important when setting priorities for software purchases that you don't limit all your purchases to pleasurable pursuits. When making copyright software buy, be sure that you are getting the best possible product for your money. I've seen so many people spend foolishly for one product because it is the most common product on the market when another less expensive product would have been completely adequate at far less than half the price. Most people never use the bells and whistles they pay for when purchasing software. The best way to be sure that you are getting the best copyright software buy you can possibly get is to make a list of things you need your software to do, the things you'd like it to, and find all the software on the market that does those things. Find the one with the lowest cost and the most necessary features and let that be the software you decide to purchase. Don't make these decisions on the spur of the moment as you will almost always cost yourself more money in the long run. Another way to insure that you are getting a great copyright software buy is by comparing prices at local and online stores before making the purchase. You might be surprised by where you will find the lowest price (also keep in mind shipping costs when purchasing online they do swing the vote sometimes). Comparative pricing can save you hundreds of dollars in the course of a year on personal software and quite literally thousands of dollars each year on professional software. Be sure to make those decisions wisely as money spent poorly is money that could have been spent elsewhere. You should always remember when comparing prices and searching for the deal of the century when it comes to copyright software buy from a reputable source. This shouldn't have to be said but it really must be said. You would be amazed at how many people have received pirated software from purchases they've made online. This is an especially bad things for business deals in which the software was needed rather than personal software that was merely wanted and looked forward to. In business you could very well loose your investment in the pirated software as well valuable time getting the copyright software buy you actually needed in the first place. While the costs of doing business locally are often more expensive than it can be online I do recommend that for some purchases, particularly copyright software buy locally even if it is a little more costly. It's nice to know that there's a person on the other side if something goes wrong and that they want your business and want people in the community to respect their business. In other words local businesses are much more likely to give the personal touch and protect their reputations by doing the right thing. There are many other reasons that buying locally is good for you and your business buying needs. Buying locally for your business will establish your business locally (this is especially good if you don't have a huge presence or massive storefront from which to advertise). It also helps you make important business contacts in order to help your local business grow. For your copyright software buy locally to have some degree of assurance about the product you are getting.
Achieving a Better Family and Work Balance Makes for Better Job Performance Are you constantly working after hours and weekends at the office? Are beginning to forget what your family even looks like? Many people find themselves in this predicament. Work seems to get more and more demanding with every passing day, and to stay on top of your game at work, you feel like you need to put in long hours. The flipside to this is that of course when you are at the office, you are away from home ? away from family dinners, play time and your kids? sporting events or school plays. You may feel like your hands are tied ? that no matter how much you want to be more involved with your family life, you have to keep working as hard as ever to make sure your family is provided for in the long run. The truth is, however, that you may be doing yourself a disservice on both fronts. Studies have shown time and again that well rested workers with well balanced lives are more productive in the time they do spend working. In the end, the best way to be a stand out worker at the office is to be fully involved and present in your family live. But wait, you say, ?I?m working practically around the clock now, and everything still isn?t getting done.? However, maybe the problem isn?t that you aren?t working hard enough. Maybe the problem instead is that you aren?t working smart enough. Think about the way you spend you working day. Are you taking on more responsibility than you need to, instead of delegating tasks to others? Are you spending a lot of time chatting in the break room when you run for a cup of coffee? Are you procrastinating so that big projects require you to work all-nighters instead of spreading out the work? Keep a journal of all of your activities at work for a few days. You might be surprised to see how you are really spending your time and in what areas you could make improvements. Simply staying on task and delegating effectively could get you home in time for dinner. When you have done everything you can to make your work habits as productive as possible, it is time to turn to other ways to balance your work life and your family life. Rule number one is the hardest one for most people to follow you ? draw clear lines of distinction between work time and family time. Family time isn?t really family time if you are constantly on your cell phone making and receiving work calls or if you are on your laptop for the entire family vacation. When you?re working ? work. When you?re with your family ? concentrate on them. The time you spend actually taking a breather from work will recharge your batteries and make you a better worker when work time rolls around again. Next, you have to evaluate your priorities. Maybe working around the clock will help you make partner faster, but at what cost? Decide if seeing your daughter?s soccer game every week is more important to you than moving up the corporate ladder quickly, and make adjustments in your schedule appropriately. There is no right or wrong answer, but deciding where you priorities lie will make scheduling easier for you. With your priorities in mind, see what work options are available to you to help you meet them. If you want more time with the kids, see if your office offers flex time or part time hours to help you meet your family commitments. Last but not least, don?t feel guilty about taking time with your family. Not only is this time important to your family, you can rest assured that the time out from the office stress will make you more productive when you return to work.
