==IPv4 interlink==
We provide a block of 8 IPv4 addresses (a /29). As usual the first and last are not usable (network and broadcast) leaving 6 usable addresses. 3 of these are for our use and 3 are usable by you.
For example, if you've been assigned 192.0.2.0/29
{| class="wikitable"
| 192.0.2.0 || Unusable
|-
| 192.0.2.1 || Virtual gateway address
|-
| 192.0.2.2 || A router address
|-
| 192.0.2.3 || B router address
|-
| 192.0.2.4 || For your use
|-
| 192.0.2.5 || For your use
|-
| 192.0.2.6 || For your use
|-
| 192.0.2.7 || Broadcast
|}
==IPv6 interlink==
For IPv6 we will allocate two addresses, one for each of our routers and announce these as router addresses. You should configure your firewall/router to configure its IPv6 external address automatically. If we shut down a router for maintenance it will announce itself as the low priority router before shutting down so as to ensure you switch to the other router automatically.
For example, if you've been assigned 2001:8b0:1628:4000/64
{| class="wikitable"
!Example IP || Use description
|-
|2001:8b0:1628:4000::4 || Customer router (for example)
|}
You can set DNS manually to 2001:8b0::2020 and 2001:8b0::2021.
