I'm seeing a DNS problem I cannot fathom: # host 65.171.152.29 Host 29.152.171.65.in-addr.arpa not found: 2(SERVFAIL)
Hm. So who's authoritative? # host -t ns 171.65.in-addr.arpa 171.65.in-addr.arpa name server ns1-auth.sprintlink.net. 171.65.in-addr.arpa name server ns3-auth.sprintlink.net. 171.65.in-addr.arpa name server ns2-auth.sprintlink.net. Asking those yields: # dig @ns1-auth.sprintlink.net. 29.152.171.65.in-addr.arpa ;; QUESTION SECTION: ;29.152.171.65.in-addr.arpa.
