When you connect to researchIT CT resources, the database vendors' systems read your computer's IP address to verify that it matches any of the IP addresses of institutions that are authorized to access those resources. These addresses (or address ranges) are registered within the vendors' systems and are checked each time a researchIT CT user connects to them.
Register your "public" Internet addresses - the IP addresses that are registered with the InterNIC Registration Service. Within an isolated network, IP addresses can be assigned at random, as long as each one is unique. However, connecting a private network (your school or library network) to the Internet requires using registered IP address (called Internet addresses) to avoid duplicates.
The format of an IP address is a 32-bit numeric address written as four numbers separated by periods. Each number can be zero to 255. For example, 188.8.131.52 could be an IP address.
As a general rule, the following IP addresses are NOT public and cannot be used for IP authentication:
Use What Is My IP Address or https://www.vpnmentor.com/tools/ipinfo/ to display the current public IP address of a computer. The IP address that displays should be equal to or within the range of the IP addresses that you're registering.
DSL or cable modem users:
DSL and cable modem Internet service can be purchased with or without static IP addresses. For example, SNET offers static IP addresses as part of their Professional DSL Internet Service but their Standard DSL Internet Service does not provide static IP addresses. Services that provide static IP addresses are generally more expensive than those that do not.
Schools and public libraries subscribing to DSL or cable modem service with static IPs: Register these IPs with researchIT CT and patrons using researchIT CT resources from within the library will not be required to enter a library card barcode.
Schools or libraries subscribing to DSL or cable internet service without static IPs: Your patrons will be asked to enter a valid Connecticut library card barcode each time they connect to researchIT CT resources.
