Glue records between TLDs

NSD
1

I have my mail server as mail1.cibolo.us and many domains in.com.
I run nameservers ns1.cibolo.us ns2.cibolo.us.

I noticed from

https://intodns.com/casitageorge.com (and all the .com domains handled by ns1.cibolo.us)

"The parent nameserver l.gtld-servers.net is not sending out GLUE for every nameservers listed,
.
This happens a lot if you have nameservers on different TLD (domain.com for example with nameserver ns.domain.org.)"

Does this mean I should set up a nameserver for each range of TLDs?

Might this resolve in a couple of days after I fixed my secondary name server ns2.cibolo.us?

I am wanting to set up DNSSEC, and want to start off right so I don't have to redo much.

Thanks, John Griessen

John Griessen:

"The parent nameserver l.gtld-servers.net is not sending out GLUE for every nameservers listed,

.com nameservers may tell you "nameservers for casitageorge.com are ..."
but as the answer is "ns1.cibolo.us" the .com nameservers have no idea about the IP.
A resolver have to ask .us nameservers to get them. That's what the statement above like to tell you.
So: it's OK...

Btw:
I prefer https://zonemaster.net to make such checks.
And that tool found "Nameserver ns2.cibolo.us has an IP address (104.245.34.178) without PTR configured."

Hi John,

the intodns.com test is giving the wrong recommendation here. I wrote a
piece about the picking the good nameserver setup a while ago, if you
