Analysis

IP Addresses

ceeor.com has exactly one IP address — 212.57.34.37.

healtheconomics.cz, ceeor.hu, vesalia.at plus two other host names have IP numbers in common with ceeor.com.

Name Servers

Four name servers handle the delegation for ceeor.com: ns1.dnsbackup.net, ns2.dnsbackup.net, ns1.nameserver.sk and ns2.nameserver.sk.

ceeor.com partially shares its NS delegation with several other domains, including mayro.sk, obut.sk, posas.cz and two others.

These name servers regularly co-occur with the name servers ns.axfone.cz, ns.axfone.eu and ns.axfone.sk.

ns1.dnsbackup.net points to 178.62.60.201 and 2a03:b0c0:1:d0::1090:2001. ns2.dnsbackup.net and ns1.nameserver.sk both point to 185.65.223.35 and 2a00:1e40:a:53::5. ns2.nameserver.sk points to 217.31.48.201 and 2001:1ab0:7e1e:2::5. Each of the four hosts ns1.dnsbackup.net, ns2.dnsbackup.net, ns1.nameserver.sk and ns2.nameserver.sk has exactly two IP addresses.

Both ns2.dnsbackup.net and ns1.nameserver.sk resolve to 2a00:1e40:a:53::5 IP addresses each.

Both ns2.dnsbackup.net and ns1.nameserver.sk resolve to 185.65.223.35 IP addresses each.

Mail Servers

ceeor.com is handled by five mail servers: mailin.mx-hub.cz, mailin.mx-hub.eu, mailin.mx-hub.net and two others.

At least some of the mail servers used by ceeor.com are shared with other domains: slcpartners.sk, lurosk.com, najom.sk and two others among them.

These mail servers tend to be used in conjunction with the mail servers mailin.mx-hub.sk.

Hosts with 8 IP addresses each:

Hostname ceeor-com.mail.protection.outlook.com directs to 52.101.68.16, 52.101.73.12 and 52.101.73.22 along with 5 other IP addresses.
