INFO Domain NS Records
Nameserver records returned by the parent servers are:

Domain IP Address TTL
ns18.xincache.com 3599
ns17.xincache.com 3599
PASS TLD Parent Check
Good. h.gtld-servers.net, the parent server I interrogated, has information for your TLD. This is a good thing as there are some other domain extensions like "co.us" for example that are missing a direct check.
PASS Nameservers Are Listed
Good. The parent server h.gtld-servers.net has your nameservers listed. This is a must if you want to be found as anyone that does not know your DNS servers will first ask the parent nameservers.
FAIL DNS Parent Sent Glue
This is bad. The parent nameserver is not sending GLUE for your nameservers.
PASS Nameserver A Records
Good. Every nameserver listed has A records. This is a must if you want to be found..

The glue records from your parent name servers do not match the glue recordsfrom your nameservers.

Good. All nameservers listed at the parent server responded.
