feat: Remove need for external API for whois lookups

[Lissy93]

Hiya,

This is a curtesy PR as I'm going to be implementing auth into who-dat.as93.net (the WHOIS API that you are using here), as in the last 2 months, your application has been sending a LOT of traffic my way, and I've unfortunately ended up with a pretty big compute bill.

In the future, I recommend that if you want to use mine or another devs hosted services commercially or publicly, it would help if you could let them know in advance, so they can pre-emptively ensure it scales efficiently and affordably. Because this has slightly ruined my Christmas!

P.s this PR is just a concept, you might want to edit it to better meet your users needs. Or let me know if you'd like me to make any changes or help with anything.

Cheers,
Alicia
