Why am I getting redirected to a Neustar Landing page?

If your network settings for DNS are pointing to Neustar's Public DNS and the domain being queried falls within a filter policy defined for that network you will be redirected to a Block, Warn or Nx Domain landing page. Although very rare, sometimes a domain may be miscategorized in which case you have the option to dispute the categorization through the landing page itself.

Do we support DoH (DNS over HTTPS)?

DNS Over HTTPS support, particularly how end user apps, OS or browsers would choose which DoH to use, is still very much in early development within the IETF and among software vendors. We are watching closely and very involved in the standards process but have no firm time at which we'll be supporting DoH in our Ultra Recursive product.
