Can Adblock block on IPv6
Posted: Tue Apr 27, 2021 6:36 pm
Adblock installed, and working for IPV4.
Running Dual Stack IPV4/IPV6.
Is there a (relatively simple) way of getting adblock to return return ::/0 as well as 0.0.0.0 for adblock listed domains so that it doesn't allow ads to be served from IPV6 servers?
Or is the issue that the entries that still return ads are Aliases?
Testing / Discovery:
Added a custom blacklist entry that looked like it was serving ads: ads.api.vungle.com
Sometimes blocked, sometimes didn't.
Looked for similar issues with standard blocklist entries, to rule out black-list processing:
worked as expected.
Returned an IPV6 address.
