About IP Addresses
-
An IP address is the numeric address of a computer
connected to the Internet. The IP address is sometimes also known as the Internet
address. On most networks, each computer has its own IP address.
An IP address is not the same as a domain name or an email
address. To see the IP address of the computer you are using
right now, look at the bottom of the feedback page.
To activate your subscription to GeoScienceWorld,
you will need to give us those IP addresses which both uniquely identify
the eligible machines on your network
and allow access only to authorized users of your subscription.
All IP addresses contain 4 numeric segments, separated by
periods. A segment is either a number, an asterisk (wildcard),
or a range specified by a dash (-). See example below.
Please make sure you've correctly identified ALL needed IP
addresses. Those using addresses not registered will not have access to GeoScienceWorld.
Some institutions use proxy servers to network their environment. This means that
all the IP addresses of the computers people are using appear to our server as
a single IP address.
If your institution uses a proxy server, please ensure that the proxy
server is used only by your institution. If it is, please enter it as
part of your subscription. If the proxy server is used by people not
covered by your online subscription, please contact us to work out
a solution.
