110 /** \brief
111  *
112  * The vl_api_[ip4|ip6]_address_with_prefix_t types are used as a type to denote
113  * both an IP address and a prefix. I.e. in CIDR notation
114  * '192.168.10.1/24' the address is 192.168.10.1 and the network
115  * prefix is 192.168.10.0/24.
116  *
117  * If only an address is needed use: vl_api_address_t types and if
118  * only a network prefix is needed (i.e. no hosts bits), then use the
119  * vl_api_prefix_t types.
