v6Only property
read / write
Indicates how a bindAddress value of InternetAddress.anyIPv6
treats IPv4 addresses.
The default is false, which means it listens to any IPv4 and any IPv6 addresses.
If set to true, it only listens on any IPv6 address. That is, it will not listen on any IPv4 address.
This value has no effect if the bindAddress is not
InternetAddress.anyIPv6
. Therefore, it is not possible to listen on
both IPv4 and IPv6 loop-back addresses at the same time (not without also
listening on every IPv4 and IPv6 address too).
Implementation
bool v6Only = false
