This is because GetNameInfo is not implememted in ROS. I originally used
GetHostByAddr, but if the IP does not have a hostname, it takes a long time
for the function to return, blocking the flow of the program. This is the
reason tracert hasn't been added to the bootcd yet.

Alex's ws2_32 rewrite should solve this. I'm hoping he's used GetNameInfo,
as GetHostByAddr is depricieted anyway now in favour of this.

I also need to do testing with tracert in ROS, as it is currently untested
and will more that likely contain a few bugs. (such confidence I have in my
code :) )

I'm also wondering why node 11 and 12 are the same in the above windows
output. I haven't seen that happen before. Again, I'll look into it.

Ged.
