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

http://www.as112.net/



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.
