Question
GMS allow IP address matching in a wide range of locations throughout the products. Each time you see the address matching, it works using the same set of principles which are detailed in the Administrator’s Manual and below.
Answer
There are many areas of the software where you will need to use IP addresses rather than domain names for entering information. Here, is an explanation of the various ways in which IP addresses may be entered.
| a.b.c.d | Specific IP address |
| a.b.c.* | All IP addresses beginning a.b.c |
| a.b.c.d-e | A range of IP addresses from d to e |
| a.b.c.d/n | Use first n bits |
Note that a ‘!’ may be placed at the beginning of the address to indicate NOT.
Examples
| !194.194.194.194 | NOT IP Address 194.194.194.194 |
| 194.194.194.* | Addresses in the range 194.194.194.0 -> 194.194.194.255 |
| 194.194.194.194/22 | Addresses in the range 194.194.192.0 -> 194.194.195.255 |
| 194.194.192-195 | As above |
| 194.194.194.194/16 | Addresses in the B Class range 194.194.0.0 -> 194.194.255.255 |
