servers.json contains invalid WHOIS servers for Google-managed TLDs (.dev, .app)

[angelxmoreno]

Issue Description

The servers.json file contains invalid WHOIS server entries for several Google-managed top-level domains that no longer operate traditional WHOIS servers.

Affected Entries

"dev": "whois.nic.google",
"app": "whois.nic.google"

Problem

The hostname whois.nic.google does not exist and returns NXDOMAIN when queried:

$ nslookup whois.nic.google
** server can't find whois.nic.google: NXDOMAIN

Evidence

1. IANA official data for .dev shows no WHOIS server:

   $ whois dev | grep whois
   whois:
   

   (empty field indicates no WHOIS service)

2. DNS resolution fails for whois.nic.google

3. Google's transition to RDAP: Google Registry has moved these TLDs to RDAP-only operation

Impact

• Applications using this library experience DNS resolution errors
• Failed WHOIS queries for .dev and .app domains
• Users may incorrectly assume the library is broken

Suggested Fix

Remove or update entries for TLDs that no longer support traditional WHOIS:

// Remove these lines or mark as RDAP-only
"dev": null,
"app": null

Alternative: Add a flag/comment system to indicate RDAP-only TLDs.

Additional Context

This affects other libraries and tools that depend on servers.json as a canonical source for WHOIS server mappings. Google's newer TLDs (.dev, .app, etc.) primarily use RDAP protocol instead of traditional WHOIS.
