Internet Protocol version 6 (IPv6) uses colons (:) in its addresses instead of periods (.), which are used in Internet Protocol version 4 (IPv4) addresses. Because colons are also used as delimiters in command lines, configuration files, seed files, Add Agent commands, and class instance names, special syntax must be observed when representing a host as an IPv6 address.

The special syntax, which is identified in this appendix, does not apply to hosts that are represented as hostnames, or as hostnames that include an explicit IP version suffix (:v6v4, :v4v6, :v6, or :v4).
