RE: using public ip address on private network

It depends, it looks like the entire range belongs to Raytheon (see below). If you NAT, it looks like any other private address range, but the caveat is that if you ever have to access a host/server in that range on the Internet you will be hosed. I ran into this when I had my CCIE lab rack in a data center using the 216.145.13.0/25 range. I had a few routers at home and just used a part of that space using a GRE tunnel. Eventually I gave up the data center and just ran it at my office, but still used the routable space as a private IP range. Eventually I ran into a site that had that range and had to (finally) change it.

Best practices would dictate NOT using any public range in a private network...

Subject: using public ip address on private network

My boss is asking to use a range of networks which includes public network space (147.17.x.x). Whoud this conflict with any addressing on the internet?

Thx!
