Hi, How about a direct address 10.10.10.10 255.255.255.255 is that not the same as 10.10.10.10/32 I would agree /31 is useless in a real situation you would only have a network and a broadcast address and no node room. Teunis Hobart, Tasmania Australia On Wednesday, January 24, 2001 at 08

Yes, but on a point-to-point link, so what if you use the network number and broadcast address to identify the two nodes? If one station sends to the broadcast address it's not a problem, there's only one other station anyway! I think /31 should be allowed on point-to-point links. Priscilla A

All what's mentioned here is absolutey right, however use of /31 is allowed in routing tables, for example. Assuming the case when 2 routers are dual homed to each other serial serial 0 & serial 1 of each. You want all the traffic to use serial 0 except 2 specific hosts (mission critical servers)
