RFC1918

Address Allocation for Private Internets

RFC1918

• 10.0.0.0/8 – 16,777,216

• 172.16.0.0/12 – 1,048,576

• 192.168.0.0/16 – 65,536

• Translation required

• Split horizon DNS

RFC1918

• 10.0.0.0/8 – reserved

• 172.16.0.0/12 – RU routed

• 192.168.0.0/16 – free for use

Resnet Address Space

• Large blocks

• Pre-assigned

• Greater security

• Improved management

• Required split horizon DNS

• No intractable problems
