URL address and port ranges for Connexion browser

Symptom
  • URL address and firewall address range
Applies to
  • Connexion browser
  • Connexion client
Resolution

Connect to OCLC via Connexion browser or Connexion client

  • When connecting, use the default address of http://connexion.oclc.org
  • If needed, the connexion.oclc.org IP address is 132.174.0.2
  • Institutions that have a firewall must configure and allow the entire network IP range 132.174.0.0/16

TCP/IP export via Connexion browser

Institutions that have a firewall must configure and allow the following:

  • Port range: 30000-30499.  All the ports in this range must be open.
  • IP address 132.174.2.0/24 (through December 2021) and 132.174.100.234

Notes for network administrators

  • ‘Ping’ of connexion.oclc.org: OCLC has disabled ICMP externally so a ‘ping’ will always fail to connexion.oclc.org
  • ’Trace route’ to connexion.oclc.org: OCLC disallows trace routes to go further than our perimeter load balancer device and they will not reach connexion.oclc.org
