Telia's service works in a way that the Internet traffic is untagged and IPTV traffic is in the VLAN(IEEE 802.1q) 4. Router has a `wan0` interface for untagged Internet traffic and a VLAN interface named `wan0.4` for IPTV. Both interfaces receive the IPv4 address and netmask via DHCP. `wan0` will get a publicly routable IPv4 address and IPTV interface will get a private IPv4 address. In addition, several v4 routes are installed by DHCP. Few /24 publicly routable networks and the 10/8 are routed via the IPTV interface. Default route is via the Internet interface `wan0`. IPv6 part works in a way that Telia delegates a /56 prefix for LAN hosts from their /32 allocation using a DHCPv6. Internet facing interface will not get an IPv6 address and routing works using the IPv6 link local addresses:
```
