FAQ
Do institutions have specific IP address ranges assigned to them?
Yes, most institutions have at least the last two quadrants of their IP address range locked down. However, different systems may follow different number formats, resulting in a wide range of IP addresses assigned to each institution.
Can two institutions have the same IP address entered into the OCLC Service Configuration?
No, institutions cannot have overlapping IP addresses in the OCLC Service Configuration. This means that if one institution requests access to an IP address already claimed by another institution, the ranges need to be updated to accommodate the request.
How do I convert an IP address range from slash notation to dashes?
The IP address range must be converted before adding it to the Service Configuration. Service Configuration only accepts IPv4 addresses. IP ranges with slashes are CIDR. You can either ask your IT department for the IPv4 range or use a free service like https://www.ipaddressguide.com/cidr to convert the range.
Errors you might see when entering IP addresses in the OCLC Service Configuration
Bad IP address part (octet out of range [0-255]) - You need to convert the IP address from slash notation (CIDR) to dash notation (IPv4). See above for instructions.
Bad IP range (wrong number of separator dots) - Try consolidating the IP range. Where applicable, you can use an asterisk (*) to represent 0-255 for an octet.
java.lang.IllegalArgumentException: bad ip range (multiple subranges) - Try consolidating the IP range. Where applicable, you can use an asterisk (*) to represent 0-255 for an octet.
