panic in getSelfGlue

[omar-polo]

Hello,

I'm probably doing something that dt doesn't expect, because with my domain it panics:

% dt omarpolo.com
using 8.8.8.8 as resolver
.
NS |IP |LOC |ASN |ISP |rtt |Serial

NS |IP |Version |DNSSEC |ValidFrom |ValidUntil
...panic: runtime error: index out of range [0] with length 0

With some printfs I think that's because it doesn't find the IP address for the nameservers:

g.Ns [{Name:ns1.omarpolo.com. Info:[] IP:[]} {Name:ns2.omarpolo.com. Info:[] IP:[]}]
