Analysis

IP Addresses

sysma.de directs to two IP numbers, 81.169.145.150 and 2a01:238:20a:202:1150::

kantel.de, asdzxc.nl, stephis-katzenpension-brandenburg.de and two other host names share IP numbers with sysma.de.

Name Servers

sysma.de is served by two delegated name servers, docks03.rzone.de and shades08.rzone.de.

sysma.de uses the same name servers as several other domains — among them dreamfeet.de, sanartelier.com, elwie.de and two more.

sysma.de partially shares its NS delegation with several other domains, including diethard-peter.de, g23.es, dplusp.de and two others.

In DNS configurations, these name servers often share authority with shades05.rzone.de, shades20.rzone.de, shades02.rzone.de and 7 other name servers.

Each of the two host names carries two IP addresses: docks03.rzone.de points to 217.160.80.130 and 2001:8d8:fe:53:5747:2a74:d:3, and shades08.rzone.de points to 185.132.34.135 and 2607:f1c0:fe:53:185:132:34:135.

Mail Servers

sysma.de uses three mail servers — mx01.hornetsecurity.com, mx02.hornetsecurity.com and sysma-de.mail.protection.outlook.com.

sysma.de has at least partial mail server overlap with other domains such as cmp-gmbh.de, lmc-group.at, incas.de and two more.

The mail servers mx03.hornetsecurity.com and mx04.hornetsecurity.com regularly co-occur with these mail servers.

Hostnames that resolve to 8 IP addresses:

sysma-de.mail.protection.outlook.com carries IP addresses 52.101.68.5, 52.101.73.1 and 52.101.73.22, with 5 other addresses beyond those.

Hosts with just one IP address:

mx01.hornetsecurity.com points to the IP address 94.100.132.8.

mx02.hornetsecurity.com points to the IP address 94.100.136.8.
