Subject: Mobile IP client sampledevice.Princeton.EDU will be changed in the Host Database

The following device using OIT Mobile IP Service appears to have relocated 
to a network other than its "home network" permanently or for an extended 
period:

   Host Database name: sampledevice.Princeton.EDU
   Hardware address: 0:1:62:c3:4:35
   Home network: signet
   Network the device is visiting: musenet
   Time this visit began: Thu Jul 19 10:01:11 2007

OIT Mobile IP Service provides a temporary Internet address and hostname when
a device is attached to a network other than its "home network." (A "home 
network" is the IP network specified in the device's entry in the Princeton 
University Host Database.)

The service is temporary, designed for short visits or truly "mobile" devices
that remain on no single network for long.

If a device continues to visit one network (other than its home) for more than
14 days, it is presumed to have been relocated permanently or for an extended
period.  At that time, Mobile IP Service is no longer appropriate for the
device; instead, its Host Database entry should be updated to reflect its new
"home network."  Doing so will cause the device to receive static IP service
(instead of Mobile IP Service) when attached to its new home network.

This notice has been sent to you because the device above has passed the 14-day
limit.  (You are listed as a "Technical Contact" for this device in its Host
Database entry.)  

OIT will change this device's entry in the Host Database on your behalf, to
reflect that the network the device has been visiting is now the device's new 
home network.  Specifically, we will change the entry's IP-SUBNET-OR-ADDRESS 
field to match the "visited network" (identified above).  Changing this field
will cause the Host Database to discard the static IP address assigned for the
device's use on its old home network, and to assign a new static IP address
(appropriate for the new home network).

Soon you will receive email indicating that the Host Database entry has been
changed. The mail will also show the new IP address assigned for the device's
use when it is attached to its new home network. The change will take effect
within an hour after that mail is sent. After that time, please reboot the
device. (You may see some disruption to the device's network service if you
don't reboot it.) It will then receive static IP service (assuming it is still
attached to its new "home network"). It will still be able to use Mobile IP
Service (when it visits other networks).

The Host Database entry also contains BUILDING and ROOM fields indicating where
the device is located.  (These values do not indicate the device's "home
network"; they serve primarily as documentation, and sometimes assist in
troubleshooting.)  As we do not know in what building and room the device is
presently located, our change will not update those fields in the Host Database
entry.  You may wish to inspect the entry, and if necessary, update those 
fields.  To do so, visit the Host Database at:
