WHOIS tool: allow IP address input (RIR/RDAP lookup)

[futureweb]

Currently the WHOIS GUI only accepts domain names. Entering an IP address (e.g. 83.65.246.198) shows “Enter a valid Domain Name”, so IP WHOIS lookups are not possible.

Expected behavior

• Accept IPv4/IPv6 as valid input
• If input is an IP, perform a network/RIR lookup (RIPE/ARIN/APNIC/etc.), preferably via RDAP, and show allocation info (netblock/org/abuse)

Steps to reproduce

1. Open Tools -> WHOIS
2. Enter 83.65.246.198
3. Error: “Enter a valid Domain Name”

Hi @futureweb, I didn't know about RDAP yet—looks promising!

I'll check it out and see if i can replace the port 43 WHOIS lookups, and add ASN (#2255) and IP lookup support.

If i query for example RIPE, depending on the IP i get redirected to the correct registry. Need to check how this works for IP and AS.

Thanks!

Edit: Maybe i can use https://about.rdap.org/, looks like the client can handle all requests and redirect it to the correct endpoint.

Should be easy to write a client for this.
