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. I want to maximize route table manageability and router/firewall log readability. I was thinking of building this lab with the following address space:
1.0.0.0 /8 10.0.0.0 /8 100.0.0.0 /8
I need 3 distinct zones which is why I wanted to separate them out. In any case, I was wondering about the status of the 1 /8 and the 100 /8 networks. What does it mean that they are IANA reserved? Reserved for what? http://www.iana.org/assignments/ipv4-address-space
Anyone else ever use IANA reserved address spacing for lab networks? Is there anything special I need to know? I'm under the impression that as long as I stay away from special use address space, I've got no worries. http://www.rfc-editor.org/rfc/rfc3330.txt
