Glossary

Link-local IPv6 addresses are not supported

Use Global addresses instead of link-local addresses.

Link-local addresses are ambiguous and cannot be used by DevOps Code ClearCase® to resolve link-local IPv6 addresses. ClearCase® relies on host name and address translation APIs. These standard APIs do not provide adequate information to ClearCase® for link-local IPv6 addresses. Global addresses are not ambiguous. The host name API provides the information required for DevOps Code ClearCase® to use these addresses. Set up your DNS and hosts tables to return global IPv6 addresses for your ClearCase® nodes.
