The appendix of my TWeb paper has a heuristic I used to identify DNS redirections using the control data.
It's a bit confusing to read but the idea is that if you have N sites that resolve to IPs in M ASes in the control data, and these N sites resolve to a single IP in the field, then it is likely that this IP is a DNS redirection.

Some of this analysis can be done offline in the data management code too.
Add code to process DNS primitives and determine if censorship is happening
For each measurement, we will do the following:
For each country, we will:
