The Internet Service Provider
An Internet Service Provider (ISP) is the organization that provides your
connection to the Internet. The Netra Internet server is the gateway from your
local network to the Internet via the ISP’s communications server. The Netra
server on your LAN provides one end of a data communications link, such as
a direct line or modem connection. The other end of the communications link
is at the ISP’s server. (The ISP may also have other connections to other large
regional networks that make up the Internet.)
The ISP may also be responsible for providing:
•
A registered network number, if your site does not have one
•
An host addressing scheme
•
A domain name
•
Name server support
•
Security for your Internet connection
•
Route management to and from your network
•
Names of news servers and mail servers
The Netra Server Administrator
The Netra server administrator’s responsibility is to configure and administer
the Netra server and the local network. After the server is configured, the
server administrator can set up the Internet services provided by the Netra
server. Examples of such tasks are: configuring local routing, assigning host
addresses, and selecting the appropriate services and security for your site.
