Find e-mail addresses on the Internet

Tasks, tools and ways to search for e-mail addresses

Main tasks:

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

Netfind information service (available in on-line mode) and automatic address servers of the Whois type (available on-line and by e-mail) are specially designed for searching e-mail addresses of people, organizations and network nodes. They also fill their address bases automatically, permanently and in a mass order directly from the address bases of large network nodes (or looking directly into them), which contain a fairly complete set of records about their subscribers.

Basic search tools:

  • Netfind automatic help service;
  • automatic address server type Whois;
  • other types of automatic address servers;
  • Help systems Yellow pages, containing and e-mail addresses.

Additional search methods:

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

Netfind Help Desk

Netfind on one request produces a white-search in many address databases and other reference services. To use this service, you need to have a Netfind client program on your computer; if it is not available, you can use telnet (logname "netfind") on any of the Netfind servers in the world:

In addition, Netfind is also available via WWW servers:

Whois server

Whois servers perform white searches in large databases of addresses for large nodes or entire networks. The work with the whois server occurs according to certain rules (whois protocol), therefore it is desirable to use a special client program (whois client). In UNIX, such a program is called: whois, it can be set to the address of any of the whois servers to search on it. Whois servers are also available via telnet.

telnet: // mailto: HELP

telnet: // mailto: HELP

Reverse search by e-mail address (Finger)

Finger search service allows you to find a specific person by his full e-mail address. You can use it while you are in the UNIX operating system and look for subscribers on other UNIX machines (since the Internet consists of them). Finger can show the registration name of the subscriber on the remote machine (login name), some important data about him if he specified them (the name of the organization or department where he works and his phone), as well as the time he last read his email (you can determine whether he still uses his e-mail address). Many UNIX machines have a finger server that accepts requests not only for specific e-mail addresses, but also allows you to do various searches among your users.

X.500 Helpdesk

The X.500 global helpdesk combines local reference services that look like one large hierarchical reference. Access requires a special program (local X.500 client), but if it is not there, you can use any of the publicly available remote X.500 clients in the world that can be reached via telnet, through some Gopher and WWW servers, and even via e-mail:

Yellow Pages Systems

Yellow Pages usually use classifications by occupation, by output and services rendered, by geography. Sometimes they are complemented by a white search (just alphabetically).

The search engine is a cross between the Yellow and White Pages (he calls himself White Pages). It searches for people not only by its own name, but also by country, city, state, domain, hobby. On the server, you can leave information about yourself.
