Sorry for such a long title.
What you see written up there is pretty much true but unpopular. Most of the times webmasters tend to just change the nameservers which take days to propagate,and this becomes pain in their butts. Now written below is a faster way to do it.
The answer is A records. Yes, they usually take only few minutes or sometimes hours to take effect worldwide.
What are A records?(from Wikipedia)
They return a 32-bit IPv4 address, most commonly used to map hostnames to an IP address of the host.
How to implement them?
First of all, check whether your host provides you with Dns facilities. If they don’t, you should try editdns.net.
1. Note the shared ip address of your hosting account. If you use cpanel then the ip address written on the fronpage. If you don’t use cpanel, then just do a dns lookup of your host’s nameserver and get its IP address. You can use network-tools.com for this.
2. Add the following three A records to your domain:
(a) yourdomain.com – ip address you noted in the above step
(b) www.yourdomain.com – same ip address (without this record www.youdomain.com won’t work)
(c) *.yourdomain.com – same ip address (without this you won’t be able to create sub-domains using your hosting account. “*” means a wildcard entry)
You are all done and your domain will be working in a few minutes or very rarely hours.
Advantages of using A records:-
1. Faster propagation of domain.
2. You have control of other records like MX, CNAME, etc. instead transferring your controls to your host.
3. Gives you ability to use services like google apps, live domains, etc. to the full extend.
1. You won’t be able to use email accounts at your host till configure your MX records or you always have option to use google apps whcich is free.
2. Just one as far as I remember
Note: You need to use AAA records if the ip address s IPv6.
