Research adding shortcut SRV record lookup for WHOIS servers for a domain

[atc0005]

There is currently no widely extended way for determining the responsible WHOIS server for a DNS domain, though a number of methods are in common use for top-level domains (TLDs). Some registries use DNS SRV records (defined in RFC 2782[25]) to allow clients to discover the address of the WHOIS server.[26] Some WHOIS lookups require searching the procuring domain registrar to display domain owner details.
