Analysis

IP Addresses

ffer.dk directs to two IP numbers, 46.30.213.33 and 2a02:2350:5:10a:800b:3a58:75c9:b2bc

www.bournemouthcattery.com, techitout.co.uk, ns.skogssamens.se and two other host names share IP numbers with ffer.dk.

Name Servers

ffer.dk uses two name servers for its delegation: ns01.one.com and ns02.one.com.

ffer.dk uses the same name servers as several other domains — among them univeyor.se, pejstrup.eu, andyscott.it and two more.

The two host names ns01.one.com and ns02.one.com each have a pair of IP addresses: ns01.one.com has 195.206.121.10 and 2001:67c:28cc::10, and ns02.one.com has 185.10.11.10 and 2001:67c:3c0::10.

Mail Servers

Four mail servers handle email for ffer.dk: mx1.pub.mailpod14-cph3.one.com, mx2.pub.mailpod14-cph3.one.com, mx3.pub.mailpod14-cph3.one.com and mx4.pub.mailpod14-cph3.one.com.

ffer.dk has at least partial mail server overlap with other domains such as madebystorm.com, ssam.dk, globus-group.eu and two more.

Each of the four hosts mx1.pub.mailpod14-cph3.one.com, mx2.pub.mailpod14-cph3.one.com, mx3.pub.mailpod14-cph3.one.com and mx4.pub.mailpod14-cph3.one.com points to a single IP address — mx1.pub.mailpod14-cph3.one.com points to 185.10.9.212, mx2.pub.mailpod14-cph3.one.com points to 185.10.9.213, mx3.pub.mailpod14-cph3.one.com points to 185.10.9.214 and mx4.pub.mailpod14-cph3.one.com points to 185.10.9.215.
