On October 12, 2005, I talked about what is IP Address.
They are practically just numbers with dots (.) between them and also hard to remember.
Some Internet Service Providers (ISP) provides dynamic IP address which means that everytime you disconnect and reconnect back to the internet, you’ll get a different IP address than the previous one.

It’s pretty expensive to get a static ip address for running services such as FTP, WWW and etc…
Thankfully there are Dynamic DNS services!
Check out No-IP, The Dynamic DNS Leader which they claimed to be…
No-IP gets rid of the need to remember IP address, ever again.
Sign up is free and they also offers paid packages such as Plus, Enhanced, Squared and Free.
See the package comparison below.

I personally is using the FREE service and is considering to get the “Plus Managed DNS” since it’s only USD24.95/year.
I do a lot of remote access in different sites especially from my PDA to home and office computers/servers.

It’s useful, try it :)
