Hierarchy

www.tech.bio is a child of tech.bio.

IP Addresses

tech.bio refers to four IP numbers: 2606:4700:3032::ac43:cff2, 2606:4700:3036::6815:4af5, 104.21.74.245 and 172.67.207.242.

Other host names, for instance psychestudy.com.cdn.cloudflare.net, brcrestoration.com, dragonex.in, yivod.com and mail.jobsmarkt.fr share IP numbers with tech.bio.

Name Servers

tech.bio's delegation uses two name servers: cosmin.ns.cloudflare.com and opal.ns.cloudflare.com.

tech.bio uses the same name server setup as other domains, such as shamirapps.com, xn--5dbqffhlc7ckw.com, ls-magic.com, itway.co.il and shamirspark.com.

tech.bio at least partially shares name servers with other domains, including 7567888.com, yalla-shoot.team, emapa.com.br, turavakuzem.com and depend.com.tw.

These name servers are commonly used together with the name servers malavika.ns.cloudflare.com, tina.ns.cloudflare.com, olof.ns.cloudflare.com and darwin.ns.cloudflare.com.

Host names with six IP numbers:

cosmin.ns.cloudflare.com points to 2606:4700:58::a29f:2c2d, 2803:f800:50::6ca2:c32d, 2a06:98c1:50::ac40:232d, 108.162.195.45, 162.159.44.45 and 172.64.35.45.

opal.ns.cloudflare.com points to 2606:4700:50::a29f:2664, 2803:f800:50::6ca2:c264, 2a06:98c1:50::ac40:2264, 108.162.194.100, 162.159.38.100 and 172.64.34.100.

Mail Servers

tech.bio 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.

tech.bio shares at least some mail servers with other domains, for example rmwi.net, aiasacademy.it, lalomablanca.com, ns500671.ns500731.ns500671.ns500754.ns500742.ns500704.ns500688.ns500678.ns500291.ns500649.ns500291.ns500291.ns500131.lustychickser.com and tranquillawn.com.

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