<div>Hi All,</div>
<div><br>
</div>
In case you missed it, despite Easter and April Fools day, CloudFlare, in conjunction APNIC have launched a new public DNS server at 1.1.1.1 and 1.0.0.1 (IPv4) and 2606:4700:4700::1111 and 2606:4700:4007::1001 (IPv6).

<div>Quick tests have suggested it is quite fast compared with Google's resolvers (seeing an average of 23ms on queries as opposed to an average of 700ms) and sensible results on CDN queries.</div>
<div><br>
</div>
<div>While initially a 5 year research project, it does look quite promising from my 20 minute digging around.</div>
