I've noticed when I visit dnsleaktest.com using Windows 8.1 & Chrome a bunch of UK IP addresses (Belonging to my ISP) are displayed alongside the Netherlands IP address I should be appearing as (see below)
When I do the same thing on Ubuntu 15.10 & Chromium (pretty much straight out the box installation) I do not get the same issue (see below)
I've tried following several sets of instructions including the ones on the website I used to do the test (e.g. manually setting DNS address). Of note on a different computer running Windows 10 the same thing occurs and we have not managed to resolve it.
This is my first question hopefully I've not breached anything! Thanks in advance.
