It contains
<quote original posting>
a copy of the report from one of the sub-groups spawned by the US
Government's initiative to examine security of the Internet among
other information infrastructures. This sub-group worked on ISP BGP
and DNS Security and the report is a decent articulation of the of the

Nothing new or earth-shattering, I think, but of interest.'
