Hmm, since when this limit exists?

Looks like it was introduced after 2.4.20-28.9 (RHL9 kernel)

One of my newer public servers (running upper shown kernel version) have
already 23 IPv6 addresses:

# ip addr show dev eth0|grep 2001 |wc -l
     23

Mostly used for one IPv6 address per "on-IPv6-no-longer-virtual-IP-less"
Apache2 webserver.

So I have the same opinion like Pekka, 16 would be a little bit to view, 64
would be a good default value for the limit.

Just my 2 cents,
        Peter
