I don't know the exact dates, but somewhen in the first half of 2006.
About in the middle of the year I looked into the issue for a bit and
filed two bugs against irssi and xchat, asking that they randomize the
result of getaddrinfo()[1].
It's probably a fair assumption that a significant number of our users
are using a Debian-based operating system.

I'm a bit confused by this code or rather its result, mainly because it
seems that on all the etch hosts I tried it the results are distributed
(even if not evenly) over the set of IP addresses, yet this discussion
suggests that etch is affected by the Rule 9 issue. On sid the result
usually consists of a single address returned all 1000 times.
