WARN: Glue at parent nameservers

[Liebing, Stefan]

Hello @ll,

I am not new in the list but that is my first post. 

I'm wondering if I have trouble with .com domains.

Message:

WARNING. The parent servers (I checked with k.gtld-servers.net.) are not
providing glue for all your nameservers. 
This means that they are supplying the NS records (host.example.com),
but not supplying the A records (192.0.2.53), 
which can cause slightly slower connections, and may cause
incompatibilities with some non-RFC-compliant programs. 
This is perfectly acceptable behavior per the RFCs. 
This will usually occur if your DNS servers are not in the same TLD as
your domain (for example, 
a DNS server of "ns1.example.org" for the domain "example.com"). 
In this case, you can speed up the connections slightly by having NS
records that are in the same TLD as your domain.

Can I ignore this?
