Analysis

IP Addresses

security.is directs to four IP numbers, which are 104.21.95.217, 172.67.148.169, 2606:4700:3030::6815:5fd9 and 2606:4700:3033::ac43:94a9.

www.avoidfilter.net, 761dy.com, stbank1.com and two other host names share IP numbers with security.is.

Name Servers

security.is is delegated to two name servers: brenda.ns.cloudflare.com and hugh.ns.cloudflare.com.

security.is uses the same name servers as several other domains — among them meteris.fr, wptonic.com, romerock.rocks and two more.

At least some of security.is's name servers are shared with other domains, for example karatas.email, mamao.pl, xpressionevents.co.uk and two more.

These name servers tend to be used in conjunction with the name servers hans.ns.cloudflare.com.

Hostnames that resolve to 6 IP addresses:

brenda.ns.cloudflare.com resolves to 108.162.192.77, 172.64.32.77, 173.245.58.77 and 3 other IP addresses.

hugh.ns.cloudflare.com resolves to 108.162.193.117, 172.64.33.117, 173.245.59.117 and 3 other IP addresses.

Mail Servers

Five mail servers handle security.is: aspmx2.googlemail.com, aspmx3.googlemail.com, aspmx.l.google.com and two others.

security.is has at least partial mail server overlap with other domains such as d4b.com.pl, areweconnected.com, ns500768.ns500758.ns500758.ns500758.ns500758.ns500735.ns500735.ns500698.ns500736.ns500698.ns500708.ns500576.ns500619.ns500576.ns500576.ns500576.trackreceptor.com and two more.

These mail servers commonly co-occur with mail servers alt1.aspmx.l.google.com, alt2.aspmx.l.google.com, alt3.aspmx.l.google.com and 3 others.

Hostnames that resolve to two IP addresses:

aspmx2.googlemail.com points to 192.178.234.27 and 2800:3f0:4003:c14::1a.

aspmx3.googlemail.com points to 172.253.116.27 and 2a00:1450:400b:c02::1b.

aspmx.l.google.com points to 64.233.180.26 and 2607:f8b0:4004:c25::1a.

alt1.aspmx.l.google.com points to 192.178.234.26 and 2800:3f0:4003:c14::1a.

alt2.aspmx.l.google.com points to 172.253.116.27 and 2a00:1450:400b:c02::1a.

aspmx2.googlemail.com and alt1.aspmx.l.google.com are host names that each point to 2800:3f0:4003:c14::1a IP addresses.

aspmx3.googlemail.com and alt2.aspmx.l.google.com are host names that each point to 172.253.116.27 IP addresses.
