On Tuesday, July 13 between 5:00-7:00am, the production IP Address Management appliance grid will be upgraded to a new software release from the vendor (8.5.2), and an IPv6 address (2600:1f16:8b2:2e01::53) will be added to dns3.illinois.edu.
What's new:
- SSO Login via Shibboleth
- This feature was previously enabled in Jan 2021, but was subsequently disabled due to a scalability issue which has now been fixed by the vendor (Infoblox).
- The Alternative Login Method will also remain available.
- The two login methods still use two different underlying user profiles with independent GUI personalizations (as explained in Known Issues).
- We can now offer DNS Traffic Control for IPv6 targets.
- various internal fixes
How will services be affected during the maintenance window?
- During the maintenance window, IT Professionals will not be able to log in to Grid Manager (via the GUI or the API) to make DNS and DHCP configuration changes.
- Any Scheduled Tasks created in Grid Manager that have not completed before maintenance begins will be automatically removed.
- Due to the use of DHCP Failover, clients will in general still be able to obtain DHCP leases. However, if a particular DHCP Range is very nearly full and experiencing a lot of churn (old clients leaving and new clients joining the network) during the maintenance window, it is possible that some new clients joining that range may not be able to obtain leases until both servers are back online.
- DNS query resolution will not be impacted.
If you would like to preview the new software release, you may log into the development IPAM system at https://dev.ipam.illinois.edu/ (from the campus network or VPN).
