Summary

In this chapter we've covered quite a lot of technical detail on the operating of infrastructure services that keep a network running. The core of this is really the operation of DNS, which everyone running a network will interact with at some time. We've also looked at routing, firewalling and network management, all of which are likely to be issues in moderate sized networks. The other thing that we looked at was 6to4 Relay Routers and Faith as examples of the sort of infrastructure that may be useful for IPv4 and IPv6 interoperation. We've also looked how you can provide IPv6 at layer 2 without upsetting your IPv4 infrastructure.
