[ih] Internet-history Digest, Vol 21, Issue 7

I'm certainly no expert on DNS, but let me support the notion that there is
a significant difference between a basic name server (such as Postel's IEN
89 proposal, in 1979), and a robust, distributed naming capability (such as
DNS).

John Shoch

[PS:  In our parallel universe at PARC, other people (not me) had developed:
--A basic name server implemented as part of PUP in the late 70's, and
published in 1979:
http://bitsavers.trailing-edge.com/pdf/xerox/alto/ethernet/pupArch.pdf
--A more general distributed naming/binding service (the Clearinghouse)
implemented as part of XNS, and published by Oppen and Dalal in 1981:
http://bitsavers.trailing-edge.com/pdf/xerox/parc/techReports/OPD-T8103_The_Clearinghouse.pdf
