Allocations

IP addresses on the WAFreeNet use the RFC1918 IPv4 address blocks. These are in the ranges of:

  • 10.0.0.0/8 (10.0.0.0 to 10.255.255.255)
  • 172.16.0.0/12 (172.16.0.0 to 172.31.255.255)
  • 192.168.0.0/16 (192.168.0.0 to 192.168.255.255)

RFC6598 (100.64.0.0/10) has been allocated by IANA for use within carrier networks. Just like RFC1918, the address space is 'bogon' and not permitted on the public Internet routing tables. You're fine to use this space in your private networks provided your ISP isn't doing carrier grade NAT using this same address range. RFC6890 also documents some other ranges like 198.51.100.0/24 and 192.0.2.0/24 (TEST-NETs) and their purpose.

New users to WAFN are allocated out of 10.60.0.0/16. These ranges are advertised in BGP and are representative of both infrastructure and member networks. There is some use of the other address blocks in RFC1918 but these are for internal uses to the WAFreeNet. You may safely filters these out and lock your BGP policy to just 10.60.0.0/16 if using BGP or keep it really simple and only have a static route.

For BGP speakers, WAFN uses the private 2-byte ASNs from section 10 of RFC1930. This reserves BGP Autonomous System Numbers 64512 to 65535 for private use and not to be registered on the global Internet. However, this was back in 1996. BGP has seen some changes in that time, namely we now have support for 32-bit (or 4-byte) ASNs. RFC6996 allocates some 94 million additional ASNs for private use when using a 4-byte ASN. These are in the range of 4200000000 to 4294967294.
