Like this… start = ipv6-address-or-prefix / ipv4-address-or-prefix ipv6-address-or-prefix = #6.54(ip-address-or-prefix<128, 16>) ipv4-address-or-prefix = #6.52(ip-address-or-prefix<32, 4>) ip-address-or-prefix<L,S> = ip-address<S> / ip-prefix<L, S> ip-address<S> = bytes .size S ip-prefix<L, S> = [0..L, bytes .size (uint .le S)] (I wish we had a .times! No I won’t cobble that together out of three .plus — or maybe we should?) Or, if you like to repeat yourself superfluously saying the same thing twice redundantly again all over: start = ipv6-address-or-prefix / ipv4-address-or-prefix ipv6-address-or-prefix = #6.54(ipv6-address / ipv6-prefix) ipv4-address-or-prefix = #6.52(ipv4-address / ipv4-prefix) ipv6-prefix = [ipv6-prefix-length, ipv6-prefix-bytes] ipv4-prefix = [ipv4-prefix-length, ipv4-prefix-bytes] ipv6-prefix-length = 0..128 ipv4-prefix-length = 0..32 ipv6-prefix-bytes = bytes .size (uint .le 16) ipv4-prefix-bytes = bytes .size (uint .le 4) ipv6-address = bytes .size 16 ipv4-address = bytes .size 4 Grüße, Carsten
