Yes.  Using the Undernet IRC server, for example, you can add a
password field to your I: lines.  You can set things up so that
certain domains require password, or certain usernames, or whatever.

 From the ircd.conf distributed with Debian's ircd:

# I: [MANDATORY]. The I: lines are client-authorization lines. Without
# these lines, no clients will be able to connect to your server.
# Wildcards ("*") are permitted. Passwords are also permitted (clients can
# be configured to send passwords).

# Debian Default: Permit universal access
# Change this ASAP if you do not want to run a public server!
I:*::*::1

#
# Ident (for more information on this, see rfc1413) can also be used by
# placing a @ in the appropriate fields.
#
# Fields are as follows:
# I:IP-address-mask:optional password:domain-mask::connection class (opt)
#
# With a password..... This will allow anyone from anywhere to connect
# as long as they know the password ("foobar"). Note listing this I: line
# first, it will be read *last*, meaning it is the "fall-through". That
# is, anyone who doesn't match the I: lines listed below must know the
# password ("foobar") to connect.
#
#I:*@*:foobar:*@*::1
# This is a standard vanilla I: line which will permit anyone with an IP
# address starting with 128.197 OR with a hostname ending in .bu.edu to
# connect to the server. NOTE, the ircd matches on the *right-most* match,
# so if I connect as hrose at csa.bu.edu (which is hrose at 128.197.10.3) I will
# show up on irc as hrose at csa.bu.edu since that is the first match it
# found. (Even though the second match is valid).
#I:128.197.*::*.bu.edu::1
#
# using ident
#I:*@128.197.*::*@*.bu.edu::1
# and you can even specify just certain usernames running ident (as long
# as the client's site is running the ident daemon):
#I:NOMATCH::hrose at csa.bu.edu::1
# putting NOMATCH in the first field will stop the ircd from matching
# automatically against the IP address and it will force the server to
# match against the hostname. (the "NOMATCH" string is not mandatory, you
# can use any arbitrary text in the first field).
#

Hope this helps,
