You can create a virtual server that specifies a list of IP addresses and a
list of service ports. Specifying a list of addresses and ports is helpful when you
have ingress traffic from, or destined for, disparate IP addresses, and all of the
traffic requires the same set of traffic profiles and policies to be applied to it.
Depending on your use case, specifying lists of addresses and ports in a single
virtual server can reduce the number of virtual servers that you need to create for
a network configuration.
