Enable DNS to Resolve an Invalid Host Name

If you created an Orchestrator with a host name that includes an underscore or another invalid character, you can take steps that let the DNS server resolve the correct IP address from an invalid host name. This requires that you create two records in the DNS server. The first record states that the original invalid name is an alias of another canonical name.

Follow these steps:

1. In the Domain Name System, create a canonical record with new, valid host name.
2. Create a CNAME record that maps the canonical name to the original, invalid name.

In this example, my_host.mycompany.com is an alias for the canonical name (CNAME) myhost.mycompany.com.

When the DNS resolver finds a CNAME record when querying for the original resource record, it restarts the query using the CNAME instead of the original name. The canonical name that a CNAME record points to can be anywhere in the DNS.
