What are valid IP formats?
IP addresses are made up of four numeric components separated by a full stop (period). Each numeric component ranges from 0 to 255. You can express an IP range by using a hyphen (-) and you can use a wildcard within a range by using an asterisk (*)
We also support IP syntax CIDR (Classless Inter-Domain Routing) IP addresses, which use a single IP address to designate many unique IP addresses. A CIDR IP address looks like a normal IP address except that it ends with a slash followed by a number, called the IP network prefix. For example: 188.8.131.52/20
