These name servers frequently co-occur with the name servers ns51.1and1.com and ns52.1and1.com.

All four hostnames — ns-us.1and1-dns.com, ns-us.1and1-dns.de, ns-us.1and1-dns.org and ns-us.1and1-dns.us — resolve to two IP numbers apiece: ns-us.1and1-dns.com to 217.160.82.2 and 2001:8d8:fe:53:0:d9a0:5202:100; ns-us.1and1-dns.de to 217.160.80.2 and 2001:8d8:fe:53:0:d9a0:5002:100; ns-us.1and1-dns.org to 217.160.83.2 and 2001:8d8:fe:53:0:d9a0:5302:100; ns-us.1and1-dns.us to 217.160.81.2 and 2001:8d8:fe:53:0:d9a0:5102:100.

Mail Servers

The MX records for topic.us point to two mail servers: mx00.1and1.com and mx01.1and1.com.
