==DNS resolvers==

You can us our usual DNS resolvers:

You can use our usual DNS resolvers:

*217.169.20.20

*217.169.20.21

Line 71:

If you have additional IP requirements, these will be set up on your control pages and you can change the target address if you need. We will set these up to route to your gateway address initially, assuming (for IPv4) that you are using the last usable address as your firewall/router.

==DSL Fallback==

==DSL or L2TP Fallback==

Customers with an Ethernet circuit can also have one or more DSL circuits, and the IP block(s) can be configured to fall back to DSL in the case of the Ethernet going down.

Customers with an Ethernet circuit can also have one or more DSL circuits or a L2TP service, and the IP block(s) can be configured to fall back to DSL/L2TP in the case of the Ethernet going down.

This can be setup by staff, do get in touch.

As well as using ADSL or FTTC circuits for Fallback, it can also be done by using one of our 3G or 4G data SIMs, or our L2TP service.

~~Usually this~~ can be setup by staff.

==BGP==

If you are announcing addresses to us using BGP then the routing and fall-back is managed by BGP. You should set up your BGP routers to peer with the two real router addresses ("A" and "B"). If you have two BGP routers then set up a full mesh (4 peer links). In the event of any maintenance we will cleanly close BGP sessions first causing routing to switch as necessary. You will need a suitable IP assignment and AS number for BGP. We support 32 bit AS numbers.

==Firewall==

Line 92:

We will normally set up a ping to one of your addresses and provide a graph showing loss and latency on the link from each of our routers. This can be useful in debugging any issues with the fibre or your router.

Please set your firewall/router to allow pings from the three IP address on 'our' side of the interlink /29 block.

==Multiple links==
