for a few years, I've put my SMTP service on a .0 address and DNS services on .255 - its been more than a decade since CIDR notation became the norm... nothing majik abt .0 or .255 - save the bounding addresses on a block delegation. --bill On Wed, Jan 21, 2009 at 05:32:03PM -0500, Joe Abley wrote:

Curiousity about what people are using as far as addressing pools these days - lots of /24s (and excluding the end addresses), or bigger blocks?
More specifically, is anyone handing out the .0 and .255 addresses, or are there still sufficient CPE/endpoints out there which cope poorly with those addresses?
Here in AS 5645 we're avoiding handing out any v4 address whose final octet is 0 or 255, but mainly out of fear the unknown. It would be handy to see a modern study of whether stuff will still break, since being able to configure big pools instead of big piles of little ones would be a minor win.
