IPv4
IPv4 connectivity is provided by UPC Czech Republic in the form of cable internet access. We have one static public IP address and can possibly get 5 dynamic public IP addresses.
IPv6
IPv6 connectivity is provided by Hurricane Electric in the form of 6in4 tunnel. Parameters of the tunnel:
| IPv6 Tunnel Endpoints | |
| Remote endpoint IPv4 address: | 216.66.86.122 |
| Local endpoint IPv4 address: | 89.103.37.137 |
| Remote endpoint IPv6 address: | 2001:470:6e:9d3::1/64 |
| Local endpoint IPv6 address: | 2001:470:6e:9d3::2/64 |
| Routed networks | |
| Routed /64 | 2001:470:6f:9d3::/64 |
| Routed /48 | 2001:470:59ae::/48 |
| DNS resolvers | |
| Anycast IPv6 Caching Nameserver: | 2001:470:20::2 |
| Anycast IPv4 Caching Nameserver: | 74.82.42.42 |
Example configuration with linux iproute2
