6db1357c34f26079dc2516b02d712df228e3db99Jeremy Reed core of the new system was described in 1983 in RFCs 882 and
6db1357c34f26079dc2516b02d712df228e3db99Jeremy Reed 883. From 1984 to 1987, the ARPAnet (the precursor to today's
6db1357c34f26079dc2516b02d712df228e3db99Jeremy Reed Internet) became a testbed of experimentation for developing the

6db1357c34f26079dc2516b02d712df228e3db99Jeremy Reed operational network environment. New RFCs were written and
6db1357c34f26079dc2516b02d712df228e3db99Jeremy Reed published in 1987 that modified the original documents to
6db1357c34f26079dc2516b02d712df228e3db99Jeremy Reed incorporate improvements based on the working model. RFC 1034,

graduate students at the University of California at Berkeley under
a grant from the US Defense Advanced Research Projects Administration

was done by Ralph Campbell. Kevin Dunlap, a Digital Equipment Corporation

last three bytes of the hardware address. The lowest significant

>Internet Drafts (IDs) are rough-draft working documents of
the Internet Engineering Task Force. They are, in essence, RFCs
in the preliminary stages of development. Implementors are cautioned not
to regard IDs as archival, and they should not be quoted or cited
in any formal documents unless accompanied by the disclaimer that
they are "works in progress." IDs have a lifespan of six months
after which they are deleted unless updated by their authors.
