Analysis

IP Addresses

c21discovery.com maps to four IP numbers: 2606:4700:3033::ac43:9a4f, 2606:4700:3037::6815:40b9, 104.21.64.185 and 172.67.154.79.

Other host names such as eliteai.co.uk, cbvpost.com, zfjn.cn, bosmuda77angkor.site and mvnetwork.com share IPs with c21discovery.com.

Name Servers

Two name servers ned.ns.cloudflare.com and wanda.ns.cloudflare.com handle the delegation for c21discovery.com.

c21discovery.com shares the same name server setup as other domains, for example 210foothillhomes.com, atlantaprorealty.com, lodevel.com, allabouturealestate.com and jkrealty.com.

c21discovery.com at least partially shares name servers with other domains, for example noyongjin.com, kanliao12.net, djmwanga.com, bjjyqq.com and barnes-international.com.

these name servers are commonly used alongside josephine.ns.cloudflare.com name servers.

Host names with six IP numbers:

ned.ns.cloudflare.com points to 2606:4700:58::adf5:3bd2, 2803:f800:50::6ca2:c1d2, 2a06:98c1:50::ac40:21d2, 108.162.193.210, 172.64.33.210 and 173.245.59.210.

wanda.ns.cloudflare.com points to 2606:4700:50::adf5:3af0, 2803:f800:50::6ca2:c0f0, 2a06:98c1:50::ac40:20f0, 108.162.192.240, 172.64.32.240 and 173.245.58.240.

Mail Servers

c21discovery.com 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.

c21discovery.com shares at least partially some mail servers with other domains, for instance ns500758.ns500759.ns500759.ns500735.ns500735.ns500736.ns500735.ns500735.ns500698.ns500698.ns500686.ns500576.ns500576.trackreceptor.com, ns500731.ns500731.ns500731.ns500742.ns500742.ns500731.ns500671.ns500731.ns500705.ns500678.ns500291.ns500678.ns500666.ns500142.lusty(0x736c7574)z.com, ns500731.ns500742.ns500742.ns500731.ns500754.ns500731.ns500704.ns500688.ns500291.ns500671.ns500649.lustychickser.com, lavaderomipa.es and basics4biz.com.

these mail servers are often used together with aspmx2.googlemail.com, aspmx3.googlemail.com, aspmx4.googlemail.com and aspmx5.googlemail.com.

Host names with two IP numbers
