There are here multiple options around the DNS theme.
The first service is an offer to all, also non-members. It is an independant and fast resolver, as a DNS-Cache, which also accepts reccursive queries from all IP-Adresses. The server is called ns.n-ix.net and has the IP-Adress 18.104.22.168.
The second DNS-Service is only accessible to members. It is a secondary nameserver, which can be attended by any member. ISPs operate often your Nameserver in the same AS or even in the same LAN-Segment, which is therefore quiet vulnerable.
At N-IX you receive the possibility to use a neutral secondary DNS-Server.
Each member receives their own IP-Adress and a corresponding reverse point, for no hardware can be entirely safe. The secondaries are virtually all servers! To use this service, please contact us!
