Junipers, Adtran, Linux Routers, Brocade, Foundry, etc have it enabled in the code; The practice of avoiding subnet zero and the all-ones subnet eventually became obsolete with RFC1878; Cisco is the only vendor that I know of that has the commend 'ip subnet-zero'; also prior to Cisco IOS® Software Release 12.0, Cisco routers, by default, did not allow an IP address belonging to subnet zero to be configured on an interface, it is now enabled by default in the command with the option to disable it.

Excellent, would have been outstanding if it was easy to verify that the other vendors were able to use the first and last subnets in any particular subnetting scenario. but the RFC document shows first and alst subnets as being usable
