Specifying IP Addresses

IPv4

At some points, vWAF permits IP address ranges to be specified in the format:

xxx.xxx.xxx.xxx/xx

Here, all the values from the specified number up to 255 apply. The number after the forward slash describes the prefix length of an IP address. The allocation tables following the examples helps you with the meaning of the prefix length.

Element	Meaning
81.243.62.0/24	81.243.62.0 to 81.243.62.255
81.243.62.128/25	81.243.62.128 to 81.243.62.255
81.243.128.0/17	81.243.128.0 to 81.243.255.255
80.0.0.0/8	80.0.0.0 to 80.255.255.255

Element	Meaning
/8	255.0.0.0
/9	255.128.0.0
/10	255.192.0.0
/11	255.224.0.0
/12	255.240.0.0
/13	255.248.0.0
/14	255.252.0.0
/15	255. 254.0.0
/16	255.255.0.0
/17	255.255.128.0
/18	255.255.192.0
/19	255.255.224.0
/20	255.255.240.0
/21	255.255.248.0
/22	255.255.252.0
/23	255.255.254.0
/24	255.255.255.0
/25	255.255.255.128
/26	255.255.255.192
/27	255.255.255.224
/28	255.255.255.240
/29	255.255.255.248

IPv4

You can enter IPv6 addresses either as full addresses, or you can omit the zeros:

fdd4:f917:0:b532:3e07:54ff:fe23:1df5 2a01:4f8:130:8421::145

Optionally, you can add brackets:

[fdd4:f917:0:b532:3e07:54ff:fe23:1df5] [2a01:4f8:130:8421::145]

When using IPv6 addresses in combination with port numbers, brackets are required:

[2a01:4f8:130:8421::145]:8082

To specify a range of IPv6 addresses, use the following syntax:

Element	Meaning
2a01:4f8:130:8421::145/128	single IP address
2a01:4f8:130:8421::/64	subnet

Brackets are optional. For example, [2a01:4f8:130:8421::]/64 is equivalent to 2a01:4f8:130:8421::/64.
