Search for BGP Anycast IP addresses in an IPv4 CIDR Block.

Use !anycast-routes4 to search for Anycast IP addresses in an IPv4 Address Block.

!anycast-routes4 takes as an argument an IPv4 address block in CIDR notation.

Usually, you can also use !anycast-routes instead of !anycast-routes4

Examples:
!anycast-routes4 120.0.0.0/6
!anycast-routes4 2.0.0.0/7
!anycast-routes4 8.0.0.0/8
!anycast-routes4 200.0.0.0/9
!anycast-routes4 202.0.0.0/10
!anycast-routes4 15.197.0.0/255.255.0.0
!anycast-routes 1.0.0.0/8
!anycast-routes 5.104.0.0/16
!anycast-routes 218.0.0.0/8

Note:
For the most part, Anycast IP addresses are assigned to hosts in distinct physical locations and BGP-announced by multiple distinct Internet Autonomous Systems (AS). A host trying to reach an anycast IP address block is directed (by the Internet networking infrastructure) to its "nearest" AS that anounces that IP address block (the AS with the shortest AS-path from his AS).
