Is it possible to use an FQDN instead of IP address for
org.ice4j.ice.harvest.NAT_HARVESTER_PUBLIC_ADDRESS in JVB configuration ?
In the RFC of ICE I found this (section-15.1) :
An IP address SHOULD be used, but an FQDN MAY be
used in place of an IP address. In that case, when receiving an
offer or answer containing an FQDN in an a=candidate attribute,
the FQDN is looked up in the DNS first using an AAAA record
(assuming the agent supports IPv6), and if no result is found or
the agent only supports IPv4, using an A. If the DNS query
returns more than one IP address, one is chosen, and then used for
the remainder of ICE processing.
