Which host to bind.

Note: The IsString instance recognizes the following special values:

• * means HostAny - "any IPv4 or IPv6 hostname"

• *4 means HostIPv4 - "any IPv4 or IPv6 hostname, IPv4 preferred"

• !4 means HostIPv4Only - "any IPv4 hostname"

• *6 means HostIPv6@ - "any IPv4 or IPv6 hostname, IPv6 preferred"

• !6 means HostIPv6Only - "any IPv6 hostname"

Note that the permissive * values allow binding to an IPv4 or an IPv6 hostname, which means you might be able to successfully bind to a port more times than you expect (eg once on the IPv4 localhost 127.0.0.1 and again on the IPv6 localhost 0:0:0:0:0:0:0:1).

Any other value is treated as a hostname. As an example, to bind to the IPv4 local host only, use "127.0.0.1".
