Ask the ASN 112 folks how many queries their servers handle.

I have a few stats for ISC's AS112 node:
- It gets about 2300 DNS UDP queries/sec
+ about 1300/sec SOA (due to dynamic DNS updates)
+ about 1000/sec PTR - It also gets about 1200 DNS TCP connections/sec,
which appear to be mostly TKEY queries. - Today the busiest source IP address is sending
50 PTR queries/sec. Number two is 30/sec.Duane W.
