This input matcher matches IPv4 or IPv6 addresses against a list of CIDR ranges. It returns true if and only if the input IP belongs to at least one of these CIDR ranges. Internally, it uses a Level-Compressed trie, as described in the paper `IP-address lookup using LC-tries <https://www.nada.kth.se/~snilsson/publications/IP-address-lookup-using-LC-tries/>`_ by S. Nilsson and G. Karlsson. For "big" lists of IPs, this matcher is more efficient than multiple single IP matcher, that would have a linear cost.

• repeated config.core.v3.CidrRange cidr_ranges = 1

  Match if the IP belongs to any of these CIDR ranges.

• string stat_prefix = 2

  The human readable prefix to use when emitting statistics for the IP input matcher. Names in the table below are concatenated to this prefix. .. csv-table:: :header: Name, Type, Description :widths: 1, 1, 2 ip_parsing_failed, Counter, Total number of IP addresses the matcher was unable to parse
