Adsense allow third party ads

I am using adsense quite long time and i have 2 2 leader board ads on header and footer
and today i move my mouse course on that header ad its show google url in browser status and when i move my courser on footer ads its d.adroll so my questions is Adsense allow 3rd party ads as well or if not then how d.adroll ads show on my webstie whereas i never make account there

This is my website

 

Well i dont know how you have other ads if you dont put them on your website .Try to contact adsesnse and ask them about this thing

 

Adroll buys ads through Adsense for certain clients just like anyone using the Google System.

 

Thanks

 

There are thousands od adnetworks running on Google AdSense. That's why you see different URL's like adroll.

 

Thanks for your reply
