I'm wondering if there is something wrong above me at MCI? I only have a /26 
in that block.
If I host 208.252.226.196 208.252.226.196 it seems to get a proper answer. But 
if I let the query go through the root servers, it fails.

  host  208.252.226.196
Host 196.226.252.208.in-addr.arpa not found: 2(SERVFAIL)

  host  208.252.226.196 208.252.226.196
Using domain server:
Name: 208.252.226.196
Address: 208.252.226.196#53
Aliases:

196.226.252.208.in-addr.arpa is an alias for 196.192.226.252.208.in-addr.arpa.
196.192.226.252.208.in-addr.arpa domain name pointer mail.fontanawater.com.
