hello.

i want to make a botnet only with dynamic ip address. for this reason,i've registered a lot of free domain names. the problem is that when i write inside the conf file :

set my-hostname "ada.toh.info"

my eggdrop join ircnet with the numeric ip and not with the domain name.
i think its a problem of reverse dns lookup. im using windrop and windows xp.

Hello,

What i know is reverse DNS only can do with ur ISP co they have the autority to create reverse DNS for you.

He's right. Whomever is authoritative for the specific block of IP addresses your IP(s) fall into is authoritative for reverse DNS. With a non-dynamic IP address, authority is passed on to whomever handles 'forward' DNS, eg hostname and domain to a specific IP, as you are effectively 'leasing' the static IP or IPs you're using.

As far as I know, this is completely unavoidable with any dynamic IP unless your ISP is willing to update their DNS to provide reverse lookups. Considering the nature of dynamic IP assignments, this is highly unlikely to happen, and they'll likely point you at a 'business class solution' for X amount of $.

Some ISPs DO provide a way to get a single static IP at a reasonable rate of $5-$10/month, in which case it's possible you can get them to set up reverse DNS or can use another DNS service (or your own) and then set aliases for the 'secondary' domains....
