Comodo DNS

I am using Comodo Secure DNS having a comodo update today I noticed one of my networks has changed to 156 154 70 22 & 156 154 71 22 this belongs to neustar so why is Comodo changing my network connection is it for this company to spy on us.

;D

Finally, which DNS ip’s are better to use? 156.154.70.22/156.154.71.22 or 8.26.56.26/8.20.247.20?.

Both IPs works very well and very fast, but i would like that Comodo Staff answer that question.

I think the best are these: 8.26.56.26 and 8.20.247.20, it is published on the site (https://securedns.dnsbycomodo.com/)
