Can I collect the IP address of a domain via WHOIS API?

Yes, there is an optional input parameter to enable the collection of the IP address for a domain name.

If you only need the IP addresses of domains and do not require additional information, the WHOIS API alone will suffice. You can retrieve the IPs by using the &ip=1 parameter (the default is 0, where IP addresses are not fetched). See the documentation for details.

If you need additional information on IPs, we offer the following related products:

• IP Netblocks: identifies who hosts those IP addresses
• IP Geolocation: shows where those IP addresses are located
• DNS Chronicle: provides historical IP information

We do not include IP information in Newly Registered Domains because it would significantly increase the time required to collect millions of WHOIS records.

WHOIS API queries are always live calls unless we have already retrieved a successful record for that domain within the past 24 hours (or 72 hours for GoDaddy and Namecheap domains due to slower authoritative queries). You can always force a live call by setting the parameter &preferFresh=1.
