For v6 we've got 2001:8b0:856:1::/64, we also get 2001:8b0:1111:1111::617a on the ppp link to boole. | For v6 we've got 2001:8b0:856:1::/64, we also get 2001:8b0:1111:1111::617a on the ppp link to boole. | ||

boole runs bind as a nameserver and unbound as a caching resolver, they run on different ip's, it has to be done this way to make DNSSEC work. | |||
The dhcp server pokes hostnames that the dhcp clients send it into dns under '''dhcp.lan.london.hackspace.org.uk'''. The default search path is '''lan.london.hackspace.org.uk''', so if you want to lookup a hostname for a machine that is a dhcp client, e.g. '''fish''' then you'd lookup '''fish.dhcp''', this avoids problems with dhcp clients asking to be '''wpad''' etc... | |||
machines with static ip's are just under '''lan.london.hackspace.org.uk''', so you can go straight to '''babbage''', '''tesla''', etc... | |||
to flush the unbound cache run (as root, on boole): | |||
unbound-control flush_zone dhcp.lan.london.hackspace.org.uk | |||
unbound-control flush_zone rev.lan.london.hackspace.org.uk | |||
