About IP address formats
For settings that require IP addresses in the Management Console, use these accepted formats:
• IPv4 addresses—Use the format x.x.x.x, where x is a decimal value between 0 and 255, with each octet separated by periods. An IPv4 address must have three periods and four octets. Optionally, you can add a prefix (for example, 192.168.1.0/24), which specifies the subnet mask. The IPv4 prefix length can be between 1 and 32.
• IPv6 addresses—Use the format y:y:y:y:y:y:y:y, where y is a segment with a hexadecimal value between 0 and FFFF. The segments are separated by colons. A normal IPv6 address consists of eight segments. Short-form notation allows removing leading zeros in a segment and using double colons (::) to represent consecutive zero segments. The IPv6 prefix length is from 1 to 128.
Wildcard entries are allowed unless specified otherwise in the description of the setting.
Examples | Description |
|---|
192.0.2.0 | IPv4 |
203.0.113.0/24 | IPv4 where “/24” is the subnet mask prefix |
2001:0DB8:ABCD:0012:0000:0000:0000:12FF | IPv6 expanded |
2001:DB8:ABCD:12:0000:0000:0000:12FF | IPv6 with leading zeros removed |
2001:DB8:ABCD:12::12FF | IPv6 with leading zeros and all-zero segments removed |
2001:DB8:ABCD:12::12FF/64 | IPv6 with short notation and subnet mask prefix |
0.0.0.0/0 or All IPv4 | Wildcards for all single-stack IPv4 |
::/0 or All IPv6 | Wildcards for all single-stack IPv6 |
All IP | Wildcard for all IP addresses |
