Sadly, the standard library doesn't seem to offer network 
interface enumeration.

However, if you don't mind delving into platform-specific C APIs 
that are exposed by Phobos but not mentioned in the docs ([issue 
5872](https://issues.dlang.org/show_bug.cgi?id=5872)), it can be 
done. The code I found here was enough to get me started:

The key to a linux implementation was `getifaddrs()`, which can 
be found in core.sys.linux.ifaddrs.
