July 11 Changes to Penn’s DNS Servers May Affect Some Off-Campus Internet Users
On Tuesday, July 11, Penn’s Domain Name System (DNS) servers, which translate alphabetic computer names to numerical equivalents understood by other computers (e.g., www.google.com to 64.233.161.104), stopped accepting translation requests from off-campus computers. This change, announced in the May 23, 2006 Almanac, was implemented for security reasons.
The change affects only a small minority of off-campus users—those who at one time manually configured their computer to use Penn’s DNS servers rather than their Internet Service Provider’s (ISP’s) DNS servers. The vast majority of off-campus users are using their ISP’s DNS servers and are not affected.
If you find you are unable to access non-Penn Internet locations from your off-campus computer on or after July 11, you may be one of the affected minority. To solve the problem, your computer will need to be reconfigured to use your ISP’s DNS servers. For assistance, please consult the self-help information at www.upenn.edu/computing/isc/networking/dns/ or contact your ISP.
