RFC1519 is 15 years old now. I *still* heard a trainer (in a Cisco class no less) mention class A/B/C in the last few months. Some evil will obviously take generations to fully stamp out.
We've faced two issues with .255 and .0: - Using /31 links Windows tracert * * *'s on .0 addresses. Had many users who thought they knew better complain about it. - Using a .255 loopback on a Cisco 6500 SNMP requests would return from the closest interface IP address. Combined with a specific version of SNMP libraries (which I can't recall right now), this caused queries to fail. Rgds, - I. -- Ian Henderson, CCIE #14721 Senior Network Engineer, iiNet Limited
