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. -- MailScanner is like deodorant...
