Let's say there are no domains using these name servers for DNS yet. How can verify outside of my

For example, VeriSign Inc's WHOIS page allows you to look up a registered
.COM name server:
Server Name: NS1.HOSTGATOR.COM IP Address: 220.127.116.11 Registrar: ENOM, INC. Whois Server: whois.enom.com Referral URL: http://www.enom.com
Is there a standard approach for looking up this information for any TLD registry?
To clarify, I am not looking to verify the name servers a domain is set to use, e.g.:
Domain Name: HOSTGATOR.COM Registrar: ENOM, INC. Whois Server: whois.enom.com Referral URL: http://www.enom.com
Name Server: NS1.P13.DYNECT.NET
Name Server: NS2.P13.DYNECT.NET
Name Server: NS3.P13.DYNECT.NET
Name Server: NS4.P13.DYNECT.NET

Instead, I am looking for a way to query a single registered name server (e.g.
ns1.example.tld) against the registry, to find the IP address the registry has recorded for this name server (e.g.
I have contacted VeriSign for input, and it turns out that VeriSign's WHOIS lookup for name servers is proprietary. Here is their response:
In regard to your question whether you would be able to obtain any information regarding a nameserver which is registered at the registry but not currently associated with any domain, you will unfortunately not be able to obtain this information via alternative routes e.g. by performing a DiG. Nameservers are only published to the zone if they are attached to a domain, hence you won't be able to obtain this information unless said nameserver is associated with a domain. Also, a DiG may provide you with a listing of nameservers associated with a domain and their respective IP's, etc.

The second part of @Iian's answer below is correct. The name server must be associated with a domain in order to lookup the IP address the registry has on record for that name server.
