But, like they say, modern whois knows where to look, no need to use anything else, I think as long as you're not stuck trying to use macOS or something else shipping weird ancient un-updated unix tools.
If you're inclined to roll your own, I keep a set of whois server pointers at <tld>.whois.services.net so for example aero.whois.services.net is a CNAME for the whois server for .aero. I update it daily using a the info in the IANA database and a bunch of kludges to fill in the gaps. There's a similar set at <tld>.whois-servers.net which seems to be less up to date. R"s, John PS: Someday I'll do it for rDNS, too.
