ISP Caching

aidso

Hopefully someone can help here:

I am administrating a website and have changed my DNS settings to point to the new host. When I browse locally, I am still getting the old version. When I browse through a US Proxy sever, I am getting the new version. How long before Virgin Media updates their DNS caches or is there any way for me to force it?

Thank you,
A.

Agreed. If it's more than 48 hours then raise a complaint with VM. Or ... try alternative DNS servers configured locally on your PC network adaptor?

Figment

Shift + F5 or Start > Run > ipconfig /flushdns

Thanks. I've tried the local flushing but no joy. The weirdest thing is it works on my phone when connected to the same wireless router as my pc. Yet my pc is picking up the old settings.

Your DNS are cached on your PC, Router, ISP, Register etc..

So when you load a domain, it gets the IP from your Browser cache, then the OS Cache, if the domain is not found then checks the router, if the router doesn't have it caches then its requests it from the ISP. which in turn requests from the Register etc etc etc..

So if you close your browser,
Clear your OS DNS "ipconfig /flushdns"
Reboot the router,

Then.. well that's as far as you can go,
I have had to wait between 20 minutes and 48hours (well 72 for one but I didn't update it and i think they messed up)

Hope that helps
