Looks like someone wanted to assign a serial network and didn't have time
to look at their internal network assignment maps... I advise 'ip unn'
for times like that :slight_smile:

I think that it would be "a good thing" for companies to start using
the ips in RFC 1918 for internal ips on Serial Interfaces. This way, you are
able to still reach Serial interfaces via ips where ip unn you can't.

  But, to do so, you would have to have filters on. If not it could cause
problems.

Yes, this is the primary reason why we don't use unn interfaces.

Indeed .. Even tho we filter these from being announced, we still get
occassional letters from people who assume we are.
