We've been experimenting with IPv6 for years, but real deployment has been going on for only a few months. I recently noticed we had internal mail clients and servers that were getting greylisted and I wanted to whitelist our entire IPv6 block for now. My initial go at this was to add the following line to grey_whitelist:
ok IP 2610:48::/32 However dbclean produced the message: CIDR block length in 2610:48::/32 too large in line 24 of /var/dcc/grey_whitelist On looking at the source code, it appears that I can't specify a prefix shorter than /112. Since the smallest network you would normally use in IPv6 has a prefix of /64, that makes whitelisting by network block a bit difficult in IPv6. Am I reading this wrong or is there a way to do this that I've missed. -- Irelann Kerry Anderson phone: (207)561-3508 Systems and Operations Information Technology Services University of Maine System 5752 Neville Hall Orono, Maine 04469-5752
