Any good "free" dns servers to use instead of OpenDns and my ISP's?

[wasc]

Hi all,

I'm looking for fast free DNS servers to use instead of my ISP's. I've already tried OpenDNS but don't like them because of all the adverts e.t.c. they are doing if you misspell a URL.

The reason for this is we have three internet lines coming into our building at work and a firewall which intelligently routes traffic over whichever line is both quickest and available. This works nicely, however we're having a problem with DNS. You see each of our 3 ISP's will only respond to DNS requests comming from their line. Therefore if our DNS server looks up www.google.com as an example using ISP 1's DNS server but sends the request through ISP3 it times out.

I have put routing rules in, so the firewall will force DNS requests through the correct line but it's still a little slow. Therefore i'm loooking for DNS servers that will respond no matter which of our 3 lines the request comes from. I did find this IP 62.157.101.211 which is part of the ORSN but looking for more in case that IP goes down.

If any of your ISPs are half way decent they should be only too happy to allow traffic from the other connections to their name servers. Depends if they're decent though, if you're dealing with £20 a month ADSL providers forget it.

Set up your own DNS server?

Bit extreme but certainly a possibility, good experience too...

You could set up a local, caching nameserver that itself falls back to a single one of your ISP's nameservers (whichever ISP's connection it uses). That's what we have at work with two ADSL lines from different providers.

For some redundancy you could set up static routes on your local DNS server to the various ISP's ones so it would always use the relevant connection.
