    I recently switched ISP and it's fine but not found pages redirect to a place of my ISP's choice.

    ping google.co.uk
    with ISP DNS is 30ms
    with google free DNS it's 30ms

    with openDNS it's 23ms

    Advices welcome
    I'm sorry but ping is the wrong way to do this; it times the network connection between you and the server, and doesn't tell how fast the DNS lookup process itself responds. (In a side note, in a galaxy far, far away - back when dial up was annoying, but not yet embarrassing - I used to have an ISP which had no clue how to run a network, and their DNS was almost hilariously bad. Ping did give some indication, but at some point, their DNS servers would effectively stop responding, but you could still just about get a ping packet to return. The name lookup part just adds another layer that can go wrong and which isn't fully tested with just a ping.)

    openDNS also does the 'we didn't find the page you actually wanted, so here's something irrelevant' thing, and some people might find that rules them out; I find that irritating, but not a total show stopper. OTOH, at least they are doing something with DNS security, which is something that needs taking seriously.

    From what i remember, there don't seem to be good DNS benchmarking apps (I think there is one, but I don't remember the name, but it didn't do as nice a job of presenting the results as DNSbench when I last looked, ~5 years ago) for Linux, but DNSbench works well in wine.

    Seems to be exactly what you need: namebench - Open-source DNS Benchmark Utility - Google Project Hosting

    Try out namebench. It hunts down the fastest DNS servers available for your computer to use. namebench runs a fair and thorough benchmark using your web browser history, tcpdump output, or standardized datasets in order to provide an individualized recommendation. namebench is completely free and does not modify your system in any way. This project began as a 20% project at Google.

    namebench runs on Mac OS X, Windows, and UNIX, and is available with a graphical user interface as well as a command-line interface.

    I ran namebench, it seems useful.
