Specifying IP (IPv6) addresses in module parameters

In INET, TCP, UDP and all application layer modules work with both IPv4 and IPv6. Internally they use the Address C++ class, which can represent both IPv4 and IPv6 addresses.

Most modules use the L3AddressResolver C++ class to resolve addresses specified in module parameters in omnetpp.ini. L3AddressResolver accepts the following syntax:

literal IPv4 address: "186.54.66.2"
literal IPv6 address: "3011:7cd6:750b:5fd6:aba3:c231:e9f9:6a43"
module name: "server", "subnet.server[3]"
interface of a host or router: "server/eth0", "subnet.server[3]/eth0"
IPv4 or IPv6 address of a host or router: "server(ipv4)", "subnet.server[3](ipv6)"
IPv4 or IPv6 address of an interface of a host or router: "server/eth0(ipv4)", "subnet.server[3]/eth0(ipv6)"
