ITS will migrate the Network Address Translation (NAT) function for wireless service for east campus to the border firewalls. During the maintenance window wireless access will be disrupted for a short period but should recover quickly.

As a result of the change, the external IPv4 addresses of campus wireless clients will change as follows:

CURRENT           NEW
external IPv4     external IPv4 
129.255.224.0/22  129.255.248.0/24   East Campus eduroam & UI-DeviceNet
129.255.232.0/22  129.255.250.0/24   East Campus UI-Guest

If service owners have “allow” listed for the current external IPv4 address ranges to enable access to specific Internet resources, that access may be disrupted. ITS may not be aware of all of these. If you have given permissions to a Internet resource using the current ranges, please contact ITS.

These changes will not affect internal IP addresses (172.17.X.X, 172.23.X.X, etc.), wireless IPV6 addresses, or IPv4 addresses for clients using eduroam in UIHC facilities.
