IP Addresses (Tools/APIs)
Work with IP addresses (validate, get IP addresses, and so on).
InterSystems IRIS® always accepts IPv4 addresses and DNS forms of addressing (host names, with or without domain qualifiers). You can configure InterSystems IRIS to also accept IPv6 addresses; see IPv6 Support.
The special variable $SYSTEM is bound to the %SYSTEM package. This means that instead of ##class(%SYSTEM.class).method(), you can use $SYSTEM.class.method().
