AntiTracker Tiers

I’ve tried searching but can’t find a definitive answer.

On the pricing page https://www.ivpn.net/en/pricing/ it mentions that the modDNS service under the plus and pro tiers upgrade AntiTracker. However, elsewhere on the site, there is no distinction drawn between AntiTracker on Standard vs Plus/Pro tiers. The AntiTracker FAQ isn’t clear on this question either.

Is there a difference in AntiTracker functionality/options available between Standard and higher tiers? Or is AntiTracker the same regardless of tier and the higher tiers provide additional services (modDNS etc) and higher device counts?

Thanks!
