Analysis

IP Addresses

4bsystems.com points to four IP numbers: 2606:4700:3032::ac43:b066, 2606:4700:3035::6815:484d, 104.21.72.77 and 172.67.176.102.

Other host names, for instance www.georgeeustice.org.uk, copyus.net, hubeihongpei.com, mail.markdavallmotorcycles.co.uk and tuni.pe share IP numbers with 4bsystems.com.

Name Servers

4bsystems.com's delegation is to two name servers ed.ns.cloudflare.com and pam.ns.cloudflare.com.

4bsystems.com shares the same name server configuration as other domains, such as mgiboston.com, line-by-line.us, metin2.to, cloud.uipath.com and metin2.dev.

4bsystems.com at least partially shares its name servers with other domains, for instance achglobal.net, evo18.com, giffords.org, mmxsolutions.ro and diziarsivi.com.

These name servers are often used together with the name servers vasilii.ns.cloudflare.com.

Host names with six IP numbers:

ed.ns.cloudflare.com points to: 2606:4700:58::adf5:3b6f, 2803:f800:50::6ca2:c16f, 2a06:98c1:50::ac40:216f, 108.162.193.111, 172.64.33.111 and 173.245.59.111.

pam.ns.cloudflare.com points to: 2606:4700:50::adf5:3a8a, 2803:f800:50::6ca2:c08a, 2a06:98c1:50::ac40:208a, 108.162.192.138, 172.64.32.138 and 173.245.58.138.

Mail Servers

Five mail servers handle 4bsystems.com: 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.

4bsystems.com shares some mail servers with other domains, including melisasim.com, menuit.io, damoov.com, slyce.co.in and ns500759.ns500698.ns500758.ns500759.ns500698.ns500698.ns500698.ns500698.ns500698.ns500698.ns500576.ns500698.ns500576.ns500576.trackreceptor.com.

These mail servers are commonly used alongside the mail servers aspmx2.googlemail.com and aspmx3.googlemail.com.

Host names with two IP numbers:

aspmx.l.google.com points to 2607:f8b0:4023:c06::1a and 142.250.101.26.

alt1.aspmx.l.google.com points to 2800:3f0:4003:c0f::1a and 108.177.123.27.

alt2.aspmx.l.google.com points to 2607:f8b0:4023:1015::1a and 172.253.135.26.
