Chapter 2: Address Patterns

An address pattern is an IP address or hostname value that contains wild card characters or range
descriptions and thus can be used to describe a range of IP addresses or hostnames. Address patterns are
commonly used in Ranger Gateway and ZoneRanger commands and configuration tables, in order to
provide a concise mechanism for specifying a set of related addresses.
For example, all of the IP addresses in the 64.1.25.0/24 subnet, can be described using the
following address pattern:
62.1.25.*
The * wildcard character can appear in any part of the address. More specific ranges can also be
specified, such as:
64.[1-2].25.[1-10]
Wildcard characters can also be used with host names. For example:
*.company.com
or
*.*.company.com
Wildcard and non-wildcard characters cannot be combined within a part of the address. For example, the
following address patterns would not be allowed:
abc*.company.com
64.1.25.1[6-8]
In order for a hostname pattern to match a given address, the number of address parts must match. For
example, the hostname server1.company.com matches the pattern *.company.com, but the
hostname server1.payroll.company.com does not.
