IP Network Range To Be Expanded for ehpnet

To keep pace with the need for IP addresses on the ehpnet subnet, the IP network range for that subnet will be expanded on November 1 2005.

ehpnet is the subnet to which OIT Ethernet Service is connected in the following buildings: 1879 Hall, Aaron Burr Hall, the Chapel, Dickinson Hall, Marx Hall, McCosh Hall, 179 Nassau St., 185 Nassau St., 201 Nassau St., and 41 William St. (except for PU Press connections). (This list of buildings wired to ehpnet is accurate as of October 13 2005.)

During 5:00am-7:00am November 1 2005, network service will be unavailable on ehpnet.

For existing devices attached to ehpnet:

• Devices that are configured to learn their IP settings via BootP or DHCP should be rebooted by their owners after 7:00am November 1 2005.

  This will cause them to learn the new IP subnet mask.

  If the device is not rebooted, it may not function correctly on the network.

• Devices that are configured to obtain their IP settings manually should be reconfigured by their owners after 7:00am November 1 2005. The IP subnet mask must be changed from 255.255.252.0 to 255.255.248.0. After reconfiguring, the device should be rebooted.

  If the device is not reconfigured and rebooted, it may not function correctly on the network.

For new devices attached to ehpnet after 7:00am November 1 2005:

• Devices that are configured to learn their IP settings via BootP or DHCP will do so when they boot.

• Devices that are configured to obtain their IP settings manually should be configured using the new IP subnet mask (255.255.248.0), not the old one.
