I've made some nameserver changes on a web domain and DNS has been updated successfully, however, when trying to browse the URL at home my virgin cable network, it still points to the old hosting. If i turn off wifi and hit 4G, I get the new hosting perfectly fine, so my question is, how long does it take for Virgin DNS servers to replicate or does anyone know if there could be a problem? Looks like it's a regular thing with Virgin?! Cheers.
It really depends on what TTL you set on the original record and when Virgin last downloaded the record from your DNS server.
Lets say you have a typical TTL of 86400 - (24 hours) - This means that if Virgin queries the master records it will cache the entry for 24 hours, and once that period has expired - will look up the record again, at which point it will pick up any changes.
If you are expecting to change a DNS record it's best to plan ahead and actually reduce the TTL a few days before the change, then once the change is done you can increase it back to 24 hours again.
Most registrars quote 48-72 hours for changes to be propagated across the net as a whole, because of DNS caching.

I did find a dns changer utility one time when I was frequently using netflix proxies, but I never actually trusted it enough to use it - I felt safer with manual changes - and though it claimed to be one-click it had to be carefully configured in advance.
I expect any such utility would need admin privileges to run in windows ?, I am not sure if a standard user account is even allowed to edit network adapter properties
