DNS Server IP Change
In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Sep 23, 16:30 EDT
Scheduled - The IP addresses of the IS&T DNS server hosts have changed:

OLD ==> NEW
18.70.0.160 ==> 18.0.70.160
18.71.0.151 ==> 18.0.71.151
18.72.0.3 ==> 18.0.72.3

Any device configured using the IS&T DHCP servers (e.g. wireless devices, most wired devices on the standard building subnets) will automatically be updated to reflect this change.

*** For devices that are configured statically, device owners will need to manually update the device’s configured DNS nameservers to use the new IP addresses. The new IP addresses are functioning today and are already responding to DNS queries. The old IP addresses will be retired as the community completes the migration to the new IP addresses over the coming weeks.

As always, if you have questions or need assistance regarding this issue. Please contact IS&T via:
