What's a wordpress page supposed to mean?
If it is the domain of the blog -- the domain's whois has the registrant's (owners name).
blog1 =>abc.com
blog2 =>xyz.com
in Linux ssh/terminal
Code:
$ whois [domain]
$ dig @8.8.8.8 [domain]
$ dig NS @8.8.8.8 [domain]
@8.8.8.8 is Google DNS (optional)*
For windows {good luck} try a webform lookup
https://www.whois.net/
then at a command prompt
Code:
>nslookup [domain]
>ping [domain]
also try
IP Address Details - ipinfo.io
Look for similarities between the two domains.
