I ran a DNSReport on one of my sites http://dnsreport.com/tools/dnsreport...ndosagroup.com
In the "Parent" category it showed:
"OK. The parent servers have glue for your nameservers.
That means they send out the IP address of your nameservers, as well as their host names."
However in the "NS" category it showed:
"Your NS records at your nameservers are:
ns1.andosagroup.net. [no glue provided] [TTL=14400]
Perhaps someone can explain to me what this all means and whether having "no glue provided" in ns1 makes any difference..
