The preferred method for client machines to automatically find the license server is to configure a DNS service record (SRV).

A Service record (SRV record) may be added to your internal DNS system for client machines to automatically find the name and port of the Houdini License server.

Example

_sesi-lm._tcp   IN      SRV     0 0 1715 licenseserver.yourdomain.com.

1715 is the default TCP port for sesinetd (Houdini license server)
Substitute licenseserver.yourdomain.com with your license server and domain information (FQDN).

Often facilities will setup a DNS CNAME for the license server.
Having the licenses bound to the DNS CNAME is a method to configure a redundant license server.
