Analysis

IP Addresses

user.tools maps to 4 IP numbers, specifically 104.21.64.122, 172.67.185.20, 2606:4700:3031::ac43:b914 and 2606:4700:3032::6815:407a.

Two other host names, along with zlayalavka.com, formulachallenge.co.nz and mail.jf-tea.com, also share IP numbers with user.tools.

Name Servers

user.tools is delegated to two name servers: ara.ns.cloudflare.com and doug.ns.cloudflare.com.

user.tools shares its NS records with other domains, for example vaxa.com, cascade.am, allvialabs.com and two others.

There is at least partial name server overlap between user.tools and other domains — iigen.com, programyukle.net, prnewswire.com and two more among them.

These name servers tend to appear in combination with the name servers chan.ns.cloudflare.com, cameron.ns.cloudflare.com, bart.ns.cloudflare.com and sri.ns.cloudflare.com.
