I'm moving the authoritative servers for some of my V4 reverse
zones and have noticed 204.152.184.104 querying me for
180.x.x.x.in-addr.arpa over and over again. Any given /24 combination
gets several queries per day for the 180 IP. Across my class B's its
generating thousands queries per day which is not a big deal, but it
continues to query the old severs for days after the TTL's on the
delegation has expired. Hence the reason it stuck out and I started
looking at it.
I could only find sales email addresses listed for the "ISC Domain
Survey" data so I decided to try here. Its not breaking anything, I just
found it ironic that ISC's data mining was not honoring the TTL's in the
reverse zone delegations. Also, I found it annoying that they were
asking for the same reverse tens to hundreds of times over the course of
several days.
