Analysis

IP Addresses

sfoundation.com has four IP addresses: 198.49.23.144, 198.49.23.145, 198.185.159.144 and 198.185.159.145.

Among the host names that share IP numbers with sfoundation.com are northwestdbtseattle.com, mydiarytoday.com, eagcs.org and two others.

Name Servers

sfoundation.com is served by two delegated name servers, pdns1.registrar-servers.com and pdns2.registrar-servers.com.

sfoundation.com has the same name server delegation as a number of other domains, such as it-maku.com, robpinedajr.com, placestovisitincali.com and two more.

The DNS delegation for sfoundation.com at least partly coincides with that of other domains, pelhamma.gov being one example.

Each of the two host names carries two IP addresses: pdns1.registrar-servers.com points to 156.154.132.100 and 2610:a1:1024::100, and pdns2.registrar-servers.com points to 156.154.133.100 and 2610:a1:1025::100.

sfoundation.com shares at least some of its mail servers with other domains — for example fernext.com, cksports.net, naoko-store.pl and two more.

These mail servers tend to be used in conjunction with alt2.aspmx.l.google.com, alt4.aspmx.l.google.com, alt3.aspmx.l.google.com and two additional mail servers.
