<font size=2 face="sans-serif"> 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.</font>

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.</font>
