Hello friends,

I have this very odd email address found with one of our employees....
<hidden_user at 172.17.0.1>

A.f.a.i.k. 172.16.0.0 - 172.31.255.255 is:

NetRange:   172.16.0.0 - 172.31.255.255

Here's my questions:

- Given that 1918 deals with allocation issues for "private Internets", is 
there a recording entity of this special address space beyond the formal 
IANA, which details the distribution of data from any "private Internet" 
once it enters the public Internet vice versa ?

- Whom to anyone's knowledge is known to be using (for special projects) or 
perhaps misusing this 172.17.0.1 ?
Greatly appreciate some insight, off list or on list, at your leisure.

best to all,

Bertil
