The Network Information Center

The NIC is a facility available to all Internet users which

provides information to the community. There are three

means of NIC contact: network, telephone, and mail. The

network accesses are the most prevalent. Interactive access

is frequently used to do queries of NIC service overviews,

look up user and host names, and scan lists of NIC documents.

It is available by using

%telnet sri-nic.arpa

on a BSD system and following the directions provided by a

user friendly prompter. From poking around in the databases

provided one might decide that a document named NETINFO:NUG.DOC

(The Users Guide to the ARPAnet) would be worth having. It could

be retrieved via an anonymous FTP. An anonymous FTP would proceed

something like the following. (The dialogue may vary slightly

depending on the implementation of FTP you are using).

%ftp sri-nic.arpa

Connected to sri-nic.arpa.

Questions of the NIC or problems with services can be asked

of or reported to using electronic mail. The following

addresses can be used:

NIC@SRI-NIC.ARPA General user assistance, document requests

REGISTRAR@SRI-NIC.ARPA User registration and WHOIS updates

HOSTMASTER@SRI-NIC.ARPA Hostname and domain changes and updates

ACTION@SRI-NIC.ARPA SRI-NIC computer operations

SUGGESTIONS@SRI-NIC.ARPA Comments on NIC publications and services

For people without network access, or if the number of documents

is large, many of the NIC documents are available in printed

form for a small charge. One frequently ordered document for

starting sites is a compendium of major RFCs. Telephone access is

used primarily for questions or problems with network access.

(See appendix B for mail/telephone contact numbers).
