Why do i need dyndns
Hi i have been reading up on this and all the threads tell me how to set it up but not why i would need it.

So for a beginner in linux sats could you answer this please

Thanks

You dont actually need it m8, but it will make life a lot easier..
Most IP address assigned by ISP's are dynamic and change frequently, this can mean less security risks for the customer but for card sharing it is a nightmare because your peers/clients will not be able to keep up with your IP changes..
Dyndns gets around this by assigning an address to your IP & performing update checks at specified intervals so your dyndns will always have the correct IP address..

have you got any sites for the dyndns sites a few ive tryed there is a charge fee.. thanks

http://www.noip.com
http://dyn.com/dns
http://freedns.afraid.org/

I know with dyn.com, you need to sign up with credit card for trial but u can cancel within the month & keep 1 free dns.. Not sure about no IP or freedns

freedns only requires an email...i have 2 from them and infact i forgot about 1 of the accounts and a chap named josh emailed me to inform me that blah blah the account would be disabled if i did not login to the website...both have been running fine for over a year now without the mandatory login!:)
