Other networks may use different electronic mail addressing schemes within their own networks.
To be used in Internet e-mail, these addresses often need to be modified.
For example, within CompuServe an e-mail address consists only of two numbers separated by a comma:
36547,891.
To convert this to an address that can be
used on the Internet,
the comma is changed to a period and the number serves as the username.
The domain name is compuserve.com, so the
Internet address would be: 36547.891@compuserve.com
