Any experience or recommendations? Besides replace the ISA proxy…. Since it's not mine to replace. Also curious whether there's an RFC recommending against the use of .0 or .255 addresses for this reason.

Way back in the late 90's I tried this with a /23 dialup DHCP pool and quickly found that the .0 and .255 users couldn't get to some scattered web sites, though they seemed to be able to get to most of the Internet. However, a year or so ago I spun up an always-on Amazon ec2 instance with a static IP and was handed a .0 address. I still use this VM regularly and have not run into any problems with reachability for this address.
