Departmental DNS Management
OIT offers IP management in our Infoblox appliance-based solution to departments using the Service Gateway as the user interface.
U of M Network Administrators need access to the Service Gateway in order to manage their own DNS. If your department is migrated to the Service Gateway, ask your department's primary contact to grant you access. If your department is not migrated use 1-HELP (612-301-4357) for any DNS changes you need.
DNS change requests coming into 1-HELP should be escalated to the T2 Voice and Data Network Support group.
DnsSyncCheck DNS Manual Cache Management
OIT offers a DNS Cache server management tool called DnsSyncCheck. The application queries our IP Address Management appliance for reference data, systematically performs the same query on our Authoritative Slave servers as well as our Anycast Cache servers, and then compares the datum from each query to the reference. If there are any differences to the reference, the Anycast Cache is invalidated for the probed records. The DnsSyncCheck tool can be used to speed up moves or changes of DNS records.
