Please let me know if this setup is fine. > 172.16.0.0 *is all private*. As so is 172.17. 172.18 ando so on, until 172.31.0.0. In fact, the reserved address space starts on 172.16.0.1 and goes all the way through 172.31.255.254. This is what the "/12" prefix means. Note that bigger networks use smaller prefixes, and smaller networks use bigger prefixes. Your networks 172.16.2.0/24, 172.16.3.0/24 and 172.16.4.0/24 are a tiny portion of the original network. In fact, you could easily use the "255.255.248.0" (/21) netmask to describe them. _______________________________________________ ISC funds the development of this software with paid support subscriptions.
