Hey everyone,
Just wondered if anyone had any experience with making an interface listen to a whole
range of IPs without using interface aliases?
I want to use a lot of my IPv6 address space, not just one IP (I'd like to be able to
give each website hosted with File Sanctuary it's own IPv6 address), and I want to be
able to define a range of IP addresses for the server to listen on, but creating lots of
interface aliases, one for each IP, in /etc/network/interfaces is going to be a) ugly and
b) probably very bad practice.
Googling mostly points me to interface aliases, but there has to be a better way?

I don't believe there is anything wrong with lots of IP aliases
using "ip -6 addr add ..."
I don't know how to achieve what you're trying to do in any other
way, but I'd be interested to hear. Maybe you could do a NAT to a
single IPv6 or something. Adding addresses sounds better. :)
Cheers,
Andy

I managed to do this by accident once, but not sure how well it'd work.
Something like "ip -6 ro add 2001::xxx/64 dev lo" might work. Although
last time I managed it it was with v4 and quagga.

You might be able to subnet your ip6 allocation and
route it to the lo

That won't actually let apache listen on them all though, will it?
Or if apache listens on *:80 will it catch that?

I don't think this works unless you explicitly proxy-NDP for each address too ('ip
neigh add proxy ...' and set a bunch of flags in /proc/sys/net/...), in which case you
might as well just 'ip -6 addr add ...' them all individually.
