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.
Steps on Reinventing yourself to Land a Better Job Having a decent job can greatly improve the quality of your life. You probably spend a fair amount of time at work. With that in mind, you do not want to be miserable when you are at work. If you want a better job, make yourself more attractive to employers. This task may be easier than you think. Start making some simple changes and watch the job offers begin to appear. The number one way to reinvent yourself in order to land a better job is to reform your attitude. Even if you are working at a nightmare of a job at the moment, you need to fight to stay positive. That negativity can be seen a mile away. You may not realize it but your face expression, posture and quality of work give off your frustration. This attitude is the first thing that has to go. Simple ways to change the way you feel about your current job include being on time and in uniform or proper dress code. These are two easy steps that will give you more pride about yourself. If you are out of dress code and late, you are not just making statement about the job. You are making a statement about yourself. Change these aspects of your working environment and you will be on your way to increasing positive energy. Take some classes. Whether you have a degree or not, brushing up on skills is always a good idea. No matter what your schedule is like, you can find time for a class or two. Use the Internet and take online classes if time is a major issue. Work at your own pace and pick up new skills. A degree or a couple of classes will make you more attractive to employers. Move away. If you are tired of dust collecting on your Communications degree while you wait tables, move to a place where your degree is more marketable. Find an area where the job market is fertile. When the economy goes south, certain job types are completely eliminated. If you are eager to find a better job you may have to go somewhere else to do it. Apply for higher positions in the company that you currently work for at the moment. Even if you are not really that thrilled about the current company you work for, while you are there you should make the best of it. Get as much experience as you can so that you will have a nice extensive work history to refer to when you are looking for a new job. If you want a better job, do some networking. Take advantage of the people that you know that have better jobs. Surround yourself with people that are working at jobs that they enjoy or are successful at. This is a great way to pave the way for yourself to get a better job. Figure out what type of job you want before you start looking. Narrow down the search and target the positions that fall in line with the jobs that you are most interested in. If you a constantly saying that you want a better job but don’t have any idea what the better job is, you are not going to be very successful in you search. Have a job in mind before you start your search. Join networking sites. These sites can be used for networking for jobs among other things. Be sure that you take the professional route when you put up your page. Let employers know that you are serious about finding a job. Do not post pictures of yourself at parties or in questionable positions. Being Effective in Your Persuasive Writing (persuasive writing) The goal of persuasive writing is to have the ability to influence or change a persons mind with your words. You encounter these in your normal everyday life. Whether it is a politician trying to convince you to vote for them, a commercial for a company that wants you to buy there product, or from your children trying to explain the reason why they should be allowed to go to that concert, persuasion is all around. You may even use the power of persuasion on yourself, like deciding why or why not you should eat that last piece of pizza or if you really need to buy another white shirt even though it is a really good deal. Everyday you have to decide on whether one choice is better than another and why. To succeed in your persuasive writing venture you need to follow a few simple rules. You must have focus. Decide on what position you are trying to persuade. Are you for or against the topic your writing about? Choose a side and stick with it. Arguing both sides of the fence will be detrimental to your persuasion. There are three techniques that you will need to use to have convincing persuasive writing. Now you need to provide facts and evidence to support your writing. Statistics and examples are used to provide the reason people should choose you position and believe your writings. You can also include facts and evidence that demonstrate why the opposition is wrong. This should be eased into. Remember you are trying to persuade and convince them on why you position is better not offend or alienate them. This is called the logos technique of persuasion writing. Another persuasive writing technique is ethos. This is where you have to prove yourself to be a creditable person. To be able to make your readers believe that they should have confidence in what you are telling them. The best way to prove your credibility is to provide true and undisputable facts, be articulate, and explain why you are capable of proving this information to them. Pathos is the third technique you will use in your writing. This will appeal to the emotions of the readers. This can be the most important technique but also the most critical. It must be used with caution or you can just as easily turn the readers against you as you could bring them with you. Appealing to your readers emotions can be tricky. This must be done subtly To work this effectively you must have the ability to make the reader feel your emotions, the joy, the pain, the hurt whatever the case maybe. You need to pin point your target audience and write to appeal to them. What sounds interesting and persuasive to a teenager most likely will not work with a middle age woman. Whether you are targeting men or women will make a difference in you writings. Identify with your target audience. An example of this would be “only the cool kids will be wearing product XYZ” or “we know as a respectable home owner you will want to…..” By identifying with the intended audience it pulls them into what you are writing and how or why it pertains to them. Persuasive writings can be a challenge. You have to objective and opened minded to other positions of the topic at hand even though sometimes you don’t want too. Remembering you goal is just to persuade them why yours is better. This does not necessarily mean that the opposition is bad or wrong, just that yours is a superior choice. |
