ISP lookup caching issues?

hey everyone, following up on the ISP lookup topic from earlier. my app's being a bit of a stubborn mule lately, it seems to be caching old ISP data and keeps showing really stale network provider identification for users. like, seriously, even after folks switch networks, it's still clinging to the old ISP details, which is honestly a bit embarrassing when you're trying to show accurate info. it's like my software thinks everyone's internet connection is set in stone, lol.

so, i'm scratching my head here, how do you guys actually handle this stale ISP data problem? is there some magic trick to force a refresh of the network provider info, or am i just missing something super obvious in my implementation? these isp lookup caching issues are driving me nuts. anyone faced this before?
