Re: Collecting PTR names or IP addresses (Was: Re: IRC Bot list (crossposting))

Isn't it a good idea to collect the IP addresses rather than the ptr name? For instance, if I were an evil person in control of the ptr record of my own IP, I could easily make the name something like 1-2-3-4.dsl.verizon.net, and if you didn't collect my IP, you can never be sure you got the right details! Something like this is probably not very widespread (has anyone seen it in practice?), but I still think that for tracking purposes, ptr records are useless. IMHO.
You are right, people can change it to be whatever they like, potentially. What if they wanted to change the IP? Think about what you said, and you will see why you are wrong. Gadi.
