IAM in Service Catalog
Your department needs a new DNS name for a new service and has an existing subdomain of "department.uw.edu"
For the new service, use the Network Portal to create the DNS name "servicename.department.uw.edu"
If you need to become a member of the contact group associated with a subdomain, reach out to one of the existing "admin" contacts in the group. Any "admin" contact can manage the contact group.
