Why have you traceroute ip instead of domain?

(A bit of a missed opportunity; the author should really set a AAAA record there IMHO)

There's no actual requirement that your PTR records resolve back to the same IP. Historically very little software bothered to check, and most of the Unix-y diagnostic software has never been updated to do so...

For some reason, most IRC servers tend to do this.

Unless you send email.

you could have multiple IPs attached to a domain which could mess up this trick.

I also wonder why not use use the domain, much easier.
