DNS Changes - Who's affected?

The vast majority of individuals at Penn will not be affected by this change. Below are some details about who will and won't be affected by the upcoming changes to Penn's DNS service:

Who will NOT Be Affected

Who WILL Be Affected

  • On-campus users
  • Off-campus users who simply get their IP address and other network configuration information via DHCP
  • Off-campus users who have manually configured their systems and are using their ISP's name server settings
  • Users who get an IP address in one of Penn's IP Address ranges
    • 128.91.x.x
    • 130.91.x.x
    • 158.130.x.x
    • 165.123.x.x

Off-campus users who:

  • Are connecting to the Internet using a third- party Internet service provider (ISP) such as Comcast or Verizon or DCANet,
  • have manually configured their system to use Penn's domain name servers instead of the name servers that their ISP provides for their use.

On or before July 11, these users will need to reconfigure their system to use the name servers provided by their ISP. Here's information on how to check or change DNS settings.

If you are one of the rare people who have manually configured your computer to use Penn's name servers from an off-campus location, name service via those Penn servers will no longer work for you as of July 11. On or before that time, you'll need to reconfigure your system to use appropriate name servers provided by your ISP.

All other users will notice no difference when this change is made.
