Analysis

Name Servers

sfau.org is delegated to four name servers: ns-cloud-b1.googledomains.com, ns-cloud-b2.googledomains.com, ns-cloud-b3.googledomains.com and ns-cloud-b4.googledomains.com.

sfau.org at least partially shares name servers with other domains such as marcoscerdeira.com, indiainternet.net, telespine.net, partnerinsure.com and nouvellevoie-jduc2026.fr.

Host names with two IP numbers:

ns-cloud-b1.googledomains.com points to 2001:4860:4802:32::6b and 216.239.32.107

ns-cloud-b2.googledomains.com points to 2001:4860:4802:34::6b and 216.239.34.107

ns-cloud-b3.googledomains.com points to 2001:4860:4802:36::6b and 216.239.36.107

ns-cloud-b4.googledomains.com points to 2001:4860:4802:38::6b and 216.239.38.107

Mail Servers

sfau.org is handled by five mail servers: aspmx.l.google.com, alt1.aspmx.l.google.com, alt2.aspmx.l.google.com, alt3.aspmx.l.google.com and alt4.aspmx.l.google.com.

sfau.org shares mail servers with other domains at least in part, for instance sonicoinc.com, ns500731.ns500742.ns500731.ns500704.ns500688.ns500671.ns500705.ns500688.ns500291.ns500671.tenderladiesbz.com, pyrus.com, tumblingedge.com and aloksurana.com.

These mail servers are commonly used together with aspmx2.googlemail.com and aspmx3.googlemail.com.

Two IPs per host name:

aspmx.l.google.com points to: 2607:f8b0:4023:c06::1a and 74.125.137.26

alt1.aspmx.l.google.com points to: 2607:f8b0:4023:2801::1b and 192.178.128.26

alt2.aspmx.l.google.com points to: 2a00:1450:4013:c1e::1a and 192.178.213.26

alt3.aspmx.l.google.com points to: 2607:f8b0:4023:3003::1b and 172.253.145.26

alt4.aspmx.l.google.com points to: 2a00:1450:400c:c00::1b and 173.194.76.26

Pattern: left IDs ascend by 9 (12, 21, 30, 39, 48); each pair of targets ascend by 9 (15/18, 24/27, 33/36, 42/45, 51/54)
