For a variety of FAQs and other net.docs, see the subdirectories of
ftp.eff.org, /pub/Net_info/

For even more material:

A full set of the Internet RFC, FYI & IEN documents can be found at:

ftp.usask.ca
/pub/net-info/internet/rfc/  [RFCs & FYIs]
/pub/net-info/internet/ien/  [IENs]

ftp nis.nsf.net
/documents/ [RFC, FYIs, Drafts, you name it, all but FAQs]

and probably also at:
rtfm.mit.edu
/pub/usenet-by-group/        [FAQs]

 If you "call" at a busy time to rtfm, you'll get a note that too many are
 logged in, but (the cool part) you get a list of many mirror sites w/paths.
