For readers, bug is specifically with passing string.Empty ('') to GetHostEntry. Microsoft official docs state that this should return the machine's current IP address(es), and indeed this is the most common forum/stackoverflow advice for detecting this information at runtime. In editor and in Mono builds, the invocation works as such, but in IL2CPP builds, it results in an error
SocketException: Could not resolve host ''
with a chain of 0000 addresses in the quoted stacktrace
