M4 Blocked IPs

This page allows you to block and unblock IPs in the M4 GUI.

• Go to SECURITY -> Blocked IPs to manage blocked IPs.

• An IP can be blocked by clicking the BLOCK NEW IP button. Enter a valid IP address, select the Server, and click the BLOCK IP button It is possible to choose ALL Servers value to block IP on all servers. The to-be-blocked IP must not be local or a current server IP.

• By clicking on the UNBLOCK button an IP is unblocked. All blocking/unblocking changes will take effect in 1 minute after they are applied. Country information (flag) can take up to one hour to appear.

• In REFINE RESULTS you can search blocked IP. Possible search by a single IP or for the range using wildcard % like in the example.

Blocked IP format

It is possible to block IPs in such a format:

• Single IP, for example, 2.2.2.2
• Subnet in CIDR notation, for example, 2.2.2.0/24. Please note that CIDR notation will be automatically converted to the canonical format. For example, if you enter 2.2.2.1/24, it will be converted to 2.2.2.0/24. This is because 2.2.2.0/24 denotes the range 2.2.2.1 - 2.2.2.254, so any subnet from 2.2.2.1/24 to 2.2.2.254/24 means exactly the same range, and a canonical way to represent this is range is with 2.2.2.0/24
• IP range in format x.x.x-xx, for example 2.2.2.1-125. Please note that all IPs in the range will be blocked as separate IPs, so entering 2.2.2.1-125 would create 125 single IP entries. For this reason, we strongly recommend using subnets if possible.
