As far as I know the two publicly available whois servers for .com and .net domains are:
whois.verisign-grs.com
and
whois.crsnic.net
Questions:
- Are there others I missed?
- Does anyone know the limit of queries you can send to them from the same IP (e.g., per day, week or month)?
Best Answer
whois.verisign-grs.com
andwhois.crsnic.net
points to the same WHOIS interface.Here's the result of a dig query request.
According to the IANA database, the authoritative URL is
whois.verisign-grs.com
. However, I confirm the old one is still working.Changing the URL doesn't give you more flexibility against request limits as they point to the same interface.
Verisign doesn't disclose the WHOIS limit.
On some forums you can read it was around 1000 requests per day.
