Prolixium dot com: News >> Blog >> Funny PTRs

I had a random idea as I was swimming, today. What do PTR records for all the equal-octet (a.a.a.a, where a = *) IPs look like on the Internet?

Easy enough to find out! I excluded class E, the unspecified (0.0.0.0/8) network, and all errors (inc. NXDOMAIN):

% for i in `seq 1 223`; do host $i.$i.$i.$i|&grep -Ev '(^;;|NXDOMAIN|SERVFAIL)'; done

Interesting that Time Warner Cable has six PTRs out of the above results. 159.159.159.159 apparently returned NOERROR yet no answers were given. And, we found an RP belonging to surf.net along with some silliness from 20.20.20.20.

So, I took it a step further. I wonder who's authoritative for all of the addresses?
