I currently manage a few websites in my university. One of these websites (which is NOT hosted within the university) was shifted to another server with a different IP around 6 months back.
The problem is when someone using the university provided Internet goes to the website, he/she is SOMETIMES still directed to the old IP (not always).
This problem does not occur when accessing the website from outside the university (i.e when NOT using the university LAN). The newer IP is always returned.
I checked with the network administrators thinking that the DNS cache of the internal servers might be outdated. They said that the change in IP will take sometime to propogate to all the name servers. True, but isnt 6 months long enough?!! Anyway, they were not very helpful.
What options do i have other than changing the domain name?
I'd appreciate any solutions to this problem.
