Hello all,
As a general rule, is it best practice to assign x.x.x.0 and x.x.x.255 as host addresses on /23 and larger?  I realize that technically they are valid addresses, but does anyone assign a node or server which is a member of a /22 with a x.x.x.0 and x.x.x.255?  Is it just a manner of preference on whether or not to use them, or are there functional reasons you shouldn't; either with rfc 1918 addresses or public addresses.
Thanks in advance,
J
