June 9, 2002: The Host Database now validates traditional (seven-digit) account numbers more strictly than it did previously. We used to accept any traditional account number if the first three digits appeared on a list of valid account prefixes obtained from the University Data Mall. We now validate the entire seven-digit number against a list of active project grant numbers obtained from the Data Mall. The list of active project grant numbers is maintained by the University Controller's Office; it does not live in the Host Database. As in the past, a account number is validated only at the time it is entered (or changed) in a Host Database entry.

April 10, 2002: Temporary Unregistered Dormnet service has been tuned to change the length of service it provides. Previously it provided service for fourteen days (four days during the end of each Dormnet subscription period). Now it provides service for seven days (fourteen days during the first eight weeks of Academic Year Dormnet service). We've chosen to tune TUD because while providing fourteen days to register a new Dormnet device appears appropriate at the start of the academic year, it appears to be too long during the remainder of the school year.

March 11, 2002: Published an an overview and statement of OIT's direction for the deployment of wireless technology.

February 14, 2002: Mobile Networking Services have been enhanced. When a device is identified as a Mobile IP Camper, we no longer turn off Mobile IP service for the device. Instead we change the device's Host Database entry on behalf of the customer, specifying that the device's home network is now the network it has been visiting. After the change completes, the customer must reboot the device.

January 24, 2002: We have expanded our collection of traffic statistics. Statistics cover more of the campus data network, provide better tools to discover "busiest" connections, and include additional useful collections of related data. While continuing to monitor bit rates, we have added measurements of packet rates. The relevant pages have been reorganized; visit Monitoring: Statistics.

November 28, 2001: Mobile Networking Services have been enhanced, to reduce the likelihood devices will become Mobile IP Campers. When a device is within four days of becoming a Mobile IP Camper, we send email to the Technical Contacts listed in the device's Host Database entry, as a reminder. (We also send email to the Technical Contacts when a device is declared a Mobile IP Camper.)

August 1, 2001: The CIT Network Systems Web server formerly located at http://wwwnet.princeton.edu has moved to https://www.net.princeton.edu.

The Network Monitoring web pages operated by CIT Network Systems (URLs formerly beginning with http://netmonserver.princeton.edu) have moved to the same new Web server.

The Host Database Web server formerly located at http://heymon.princeton.edu/hostmaster/ has moved to https://www.net.princeton.edu/hostmaster/.

All the old published URLs will continue to function, but will redirect you to the new Web server. The URL paths remain the same; however the hostname in each has changed (from wwwnet.princeton.edu, netmonserver.princeton.edu, or heymon.princeton.edu) to www.net.princeton.edu. We consolidated these Web servers into a single new server to allow us to provide secure connections to those pages that need it.

The new server supports secure connections through the use of SSL or TLS. Connections secured with SSL or TLS are encrypted, and also provide assurance that the server you are talking to is who you think it is.

Any pages that require you to specify a CIT netid and password now use a secured connection. In particular, this includes all pages allowing you to add, change, or delete Host Database entries. The use of passwords over non-secured connections is no longer supported; your Web browser must support SSL or TLS to access password-protection pages.

July 8, 2001: The Devices Blocked from Mobile IP Service document (which previously showed only the Mobile IP Campers) also shows devices declared ineligible for receiving Mobile IP Service for other reasons. Similarly, the Devices Blocked from Temporary Unregistered Dormnet IP Address Service document (which previously showed only the TUD Campers) also shows devices declared ineligible for receiving TUD Service for other reasons.

April 1, 1999: Added Server Network Utilization Statistics to the Network Monitoring page.

January 8, 1999: Updated the Resources page to add a new document describing The TigerNet Host Charge. This charge was announced earlier in this letter, and takes effect February 1 1999. Most devices attached to the campus data network will be billed the TigerNet Host Charge; the charge is based upon Host Database records. Dormnet subscriptions are not subject to the TigerNet Host Charge (Dormnet service is billed through a separate subscription fee). The TigerNet Host Charge is waived for network infrastructure, printers, and some other special kinds of devices.

Revised DHCP and BootP Services to reflect the new service. Retired Network Services in the Firestone Library "Bring Your Own Computer" Facility as its unique procedures are now documented as standard in the two preceeding documents. Associated with the new service are two other new documents: Current Mobile IP Address Assignments and Devices Blocked from Mobile IP Service.

September 9, 1997: Updated Domain Name Service to remove hostnames that were displayed alongside the IP addresses of our recommended DNS servers. (The hostnames will change soon, but there should be no impact as the IP addresses will remain the same; clients are configured with DNS servers' IP addresses, not their hostnames.) The document was also updated to remove 140.180.128.12 and 140.180.128.58 from the list of recommended DNS servers; newly-configured machines configured manually with a DNS server list (i.e. they do not use DHCP or BootP to learn the current list) should avoid using those two IP addresses for DNS service, to avoid the need to any reconfiguration when those addresses are retired in the future. The document was also updated to re-order the list of recommended DNS servers to reflect the capacity of new DNS servers being installed; newly-configured machines configured manually with a DNS server list should list the servers in the new order. (There is no impact to existing machines, as they will continue to work with the servers listed in any order.)

August 22, 1997; Added a DNS Lookup tool to the Resources page.

August 18, 1997: Updated Network Services in the Firestone Library "Bring Your Own Computer" Facility to reflect that BootP clients are no longer supported in this facility as of today. This change was previously announced in Firestone Library "Bring Your Own Computer" Facility to Require DHCP.
