Analysis

IP Addresses

contexa.net refers to four IP numbers: 2606:4700:3033::ac43:caec, 2606:4700:3037::6815:e75, 104.21.14.117 and 172.67.202.236.

Other host names, for instance omnisyst-ems101.sbs, pacot.es, cybernationonline.com, tivarionexal.com and hongdaanzhuang.com share IP numbers with contexa.net.

Name Servers

contexa.net's delegation uses two name servers: amit.ns.cloudflare.com and maria.ns.cloudflare.com.

contexa.net uses the same name server setup as other domains, such as opendeal.org, accetrix.com, xzgoogle.com, spm.so and kontakt.by.

contexa.net at least partially shares name servers with other domains, including opinkerfi.dev, ashleighkwong.com, hest24.pl, siwangchang.net and com-runtime-managt.pro.

These name servers are commonly used with lindsey.ns.cloudflare.com.

Host names with six IP numbers:

amit.ns.cloudflare.com points to 2606:4700:58::adf5:3b3f, 2803:f800:50::6ca2:c13f, 2a06:98c1:50::ac40:213f, 108.162.193.63, 172.64.33.63 and 173.245.59.63.

maria.ns.cloudflare.com points to 2606:4700:50::adf5:3ac0, 2803:f800:50::6ca2:c0c0, 2a06:98c1:50::ac40:20c0, 108.162.192.192, 172.64.32.192 and 173.245.58.192.

Mail Servers

contexa.net is handled by five mail servers: aspmx2.googlemail.com, aspmx3.googlemail.com, aspmx.l.google.com, alt1.aspmx.l.google.com and alt2.aspmx.l.google.com.

contexa.net shares at least some mail servers with other domains, for example stevie.co.nz, medixocentre.com, ns500759.ns500698.ns500758.ns500758.ns500736.ns500698.ns500708.ns500576.ns500576.ns500652.ns500619.trackreceptor.com, ns500759.ns500759.ns500759.ns500698.ns500576.ns500619.ns500619.ns500652.trackreceptor.com and worklogin.com.

these mail servers are often used with alt3.aspmx.l.google.com, alt4.aspmx.l.google.com, aspmx4.googlemail.com and aspmx5.googlemail.com.

Host names with two IP numbers

aspmx2.googlemail.com points to: 2800:3f0:4003:c0f::1a and 108.177.123.26

aspmx3.googlemail.com points to: 2a00:1450:400b:c02::1a and 172.253.116.26

aspmx.l.google.com points to: 2607:f8b0:4004:c09::1a and 142.251.111.26

alt1.aspmx.l.google.com points to: 2800:3f0:4003:c0f::1b and 108.177.123.26

alt2.aspmx.l.google.com points to: 2607:f8b0:4023:3003::1a and 172.253.145.26

Host names that point to 108.177.123.26 are aspmx2.googlemail.com and alt1.aspmx.l.google.com
