Domain whois is useless, but IP whois is at least kind of useful to check before blanket banning entire IP ranges.

- homebrewer 2y agoIt's useful for checking if a domain name is taken without doing that through a registrar, which is both less convenient, and (in case of shitty registrars) can be sold to domain speculators.

- grendelt 2y agoInterestingly, when discussing WHOIS with my networking students, I discovered .edu WHOIS is not (cannot?) hidden. I suppose EDUCAUSE either requires WHOIS to remain open or they do not offer information hiding. Doing some WHOIS lookups, we found a point of contact at a university, called the network admin said hello and launched into an impromptu network admin interview. It was cool stuff. I emailed him later in the day to apologize to and thank him for being a good sport about the whole thing. He (fortunately) found it all rather enjoyable.
- kelnos 2y agoSome other TLDs, like .us and .in, also forbid WHOIS privacy. TLD owners are free to set whatever policy they want around this. Perhaps .edu does the same.
- whalesalad 2y agowhois/rdap is very useful to identify if a domain is registered or not, and if so with whom. still lots of use there without pii data.
