Domain resolve issue in OpenDNS

Hi OpenDNS,

We have problem that our CDN does not work with OpenDNS, but it works with Google and other DNS providers.

Basically customers it give an URL to our CDN "service router" e.g

The service router looks up the most suitable CDN streamer and redirects the customer to this url e.g.

But for some reason OpenDNS cannot resolve the domain: by20ttv1sr102.se.ys-hls2vod.ds.cdn.yousee.tv

When doing a "nslookup", we get this error:

> by20ttv1sr102.se.ys-hls2vod.ds.cdn.yousee.tv

Server: 208.67.222.222

Address: 208.67.222.222#53

** server can't find by20ttv1sr102.se.ys-hls2vod.ds.cdn.yousee.tv: SERVFAIL

However our own DNS and Google DNS can lookup the domain, see below:

> server 8.8.8.8

Default server: 8.8.8.8

Address: 8.8.8.8#53

> by20ttv1sr102.se.ys-hls2vod.ds.cdn.yousee.tv

Server: 8.8.8.8

Address: 8.8.8.8#53

Non-authoritative answer:

Name: by20ttv1sr102.se.ys-hls2vod.ds.cdn.yousee.tv

Address: 87.49.36.190

Do you have any idea why this happens ?
