URL address and port ranges for Connexion client

Applies to

• Connexion client

Answer

Connect to OCLC via Connexion client

• When connecting, use the default address of connexion.oclc.org
• Institutions that have a firewall must configure and allow the entire network IP range 132.174.0.0/16
• Connexion client uses standard http protocol and port 80 to connect to WorldCat.

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 (152.179.19.254) and it will not reach connexion.oclc.org
