Hello friends, I have this very odd email address found with one of our employees.... <hidden_user@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 CIDR: 172.16.0.0/12 NetName: IANA-BBLK-RESERVED NetHandle: NET-172-16-0-0-1 Parent: NET-172-0-0-0-0 NetType: IANA Special Use NameServer: BLACKHOLE-1.IANA.ORG NameServer: BLACKHOLE-2.IANA.ORG Comment: This block is reserved for special purposes. Please see RFC 1918 for additional information. RegDate: 1994-03-15 Updated: 2002-09-12 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 Bertil Fortrie hostmaster@nso.org
