This should probably go in `Networking` instead of `BrooklynNetworkUtils`.
The difference between the two classes seems to be:
* `Networking` is for generic network utility methods.
* `BrooklynNetworkUtils` is for utility methods that rely on some other
part(s) of Brooklyn, or seem too custom in how they are used/configured to be
considered a "common utility". For example `getLocalhostExternalIp()` will load
the resource `external-ip-address-resolvers.txt` that tells us about external
service(s) to use, such as http://jsonip.com/, and will contact that in a
time-limited way to get + cache the ip).
Worth adding javadoc to the two classes to that affect, and to include in
the latter a reference to `{@link org.apache.brooklyn.util.net.Networking}`.
