Analysis

Mail Server Role

iserfor.net acts as its own mail server.

mx00.1and1.fr and mx01.1and1.fr are often paired with iserfor.net as mail servers.

Name Servers

iserfor.net has four authoritative name servers: ns1089.ui-dns.biz, ns1089.ui-dns.com, ns1089.ui-dns.de and ns1089.ui-dns.org.

At least some of iserfor.net's name servers are shared with other domains, for example haspi.de, 70smemories.com, parcelaindustrial.com and two more.

These name servers tend to co-occur with ns1113.ui-dns.de, ns1069.ui-dns.com, ns1058.ui-dns.de and 7 other name servers in the same DNS delegations.

Four hostnames, each resolving to a pair of IP addresses: ns1089.ui-dns.biz directs to 217.160.81.89 and 2001:8d8:fe:53:0:d9a0:5159:100; ns1089.ui-dns.com directs to 217.160.82.89 and 2001:8d8:fe:53:0:d9a0:5259:100; ns1089.ui-dns.de directs to 185.132.32.89 and 2607:f1c0:fe:53:185:132:32:89; ns1089.ui-dns.org directs to 217.160.83.89 and 2001:8d8:fe:53:0:d9a0:5359:100.

Mail Servers

iserfor.net delegates mail handling to three mail servers: iserfor.net, mx00.1and1.fr and mx01.1and1.fr.

iserfor.net shares mail servers — at least in part — with other domains, including s288014119.onlinehome.fr, xaho.fr, www.cashsystemes.com and two others.

Each of mx00.1and1.fr and mx01.1and1.fr has one IP address: mx00.1and1.fr uses 212.227.15.41 and mx01.1and1.fr uses 217.72.192.67.
