Others have pointed out that I should stick to RFC 1918 address space. But again, this is a lab network and to use the words of another, one of the things I want to do is make it much easier to "parse visually" my route tables. Think of it as a "metric system" type of numbering plan. The 1 and 100 nets would not be advertised via BGP obviously...not a hijack situation at all. If I take into account the possibility that this lab will have later requirements to connect to the internet, all I have to do is have a NAT plan in place...one that even takes into account that the 1 and 100 nets could become available some day, correct? Thanks to those who have responded so far. -----Original Message----- From: [email protected] [mailto:[email protected]] Sent: Friday, May 30, 2003 8:08 AM To: Murphy, Brennan Cc: [email protected] Subject: Re: IANA reserved Address Space networks 1 and 100 are reserved for future delegation. network 10 is delegated for private networks, such as your lab. if you use networks 1 and 100, you are hijacking these numbers. that said, as long as your lab is never going to connect to the Internet, you may want to consider using the following prefixes: 4.0.0.0/8 38.0.0.0/8 127.0.0.0/8 192.0.0.0/8 > > > I'm tasked with coming up with an IP plan for an very large lab > network.
