ITS will migrate the Network Address Translation (NAT) function for wireless service for West Campus to the campus border firewalls. During the maintenance window campus 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
129.255.228.0/22  129.255.252.0/24   West Campus eduroam, UI-DeviceNet, and College of Dentistry
129.255.236.0/22  129.255.254.0/24   West Campus UI-Guest

If someone on campus has “allow” listed for the current external IPv4 address ranges to enable access to specific Internet resources, that access may be disrupted. Unfortunately, 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.
