Search for e-mail addresses on the Internet

Tasks, means and ways of searching for e-mail addresses

Main goals:

  • white-search for the e-mail address of a particular person;
  • white-search for the e-mail address of a particular organization;
  • white-search for an e-mail address in a specific organization;
  • white-search for the e-mail address of the host;
  • reverse white-search for the subscriber by e-mail address;
  • yellow-search for the e-mail address of the organization.
  • a special case: the search for e-mail addresses of educational institutions and their students;

To find e-mail addresses of people, organizations and network nodes, the Netfind helpdesk (available on-line) and automatic address servers like Whois (available on-line and by e-mail) are specially designed. They fill their address databases automatically, constantly and in mass order directly from the address databases of large network nodes (or search directly in them), which contain a fairly complete set of records about their subscribers.

Basic search tools:

  • automatic help service Netfind;
  • automatic address servers such as Whois;
  • automatic address servers of other types;
  • Yellow Pages reference systems containing both e-mail addresses.

Additional ways to search:

  • Special requests to automatic servers of any mass service (teleconferences or mailing lists) or receiving in any other way a list of its subscribers;
  • request to subscribers of any mass service;
  • a request to the staff of the network node;
  • a request to the automatic address server or to the personnel of any organization that provides public access to the addresses of its correspondents (customers, partners, etc.).

Netfind Help

Netfind on one request produces a white-search in many address databases and other help services. To use this service on your computer, you need to have a Netfind client program, in its absence you can use telnet (logname "netfind") on any of the Netfind servers in the world:

In addition, Netfind is also available through the WWW server:

Whois server

Whois-servers produce white-search in large databases of addresses of large nodes or entire networks. Work with whois-server occurs under certain rules (whois-protocol), so it is desirable to use a special client program (whois-client). In UNIX, such a program is called: whois, it can be set the address of any of the whois servers to search on it. Whois servers are also accessible via telnet.

telnet: // mailto: HELP

telnet: // mailto: HELP

"Reverse" Whois-search the organization for its domain (part of the e-mail address).

Reverse search by e-mail address (Finger)

The search service Finger allows you to find a specific person by his full e-mail address. It can be used while in the UNIX operating system and look for subscribers on other UNIX machines (the good is that the Internet is theirs). Finger can show the login name of the subscriber on the remote machine (login name), some important data about him, if he indicated them (the name of the organization or subdivision where he works and his phone), as well as the time when he last read his e-mail (you can determine , whether he still uses his e-mail address). Many UNIX-machines have a finger-server that accepts requests not only about specific e-mail addresses, but also allows to do various searches among their users.

X.500 Help Desk

The X.500 global help service combines local help services that look like one large hierarchical directory. Access requires a special program (local X.500 client), but if it does not, you can use any of the world's available remote X.500 clients that can be accessed via telnet, through some Gopher and WWW servers, and even via e-mail:
