Previous commit added support for IP addresses in the hostalias file but
I forgot to update the documentation in sarg.conf.
# host name found in the log.
# Host names replaced by identical aliases are grouped together in the
# reports.
-# IP addresses are processed as string. There is no support for CIDR
-# notation.
+# IP addresses are supported and accept the CIDR notation both for IPv4 and
+# IPv6 addresses.
#
# Example:
# *.gstatic.com
# *.myphone.microsoft.com:443 *.myphone.microsoft.com:secure
# *.freeav.net antivirus:freeav
# *.mail.live.com
-# 65.55.33.119 *.mail.live.com
+# 65.52.00.00/14 *.mail.live.com
#hostalias /usr/local/sarg/hostalias
