What is mopub.com?
mopub.com is the domain associated with MoPub, a mobile ad mediation and monetization platform. Originally an independent company, MoPub was acquired by Twitter in 2013 and later sold to AppLovin Corporation in January 2022 for $1.1 billion. Since then, AppLovin operates the service under the MoPub brand.
Who operates mopub.com?
AppLovin Corporation, headquartered in Palo Alto, California, is the parent company. Founded in 2012, AppLovin provides mobile advertising, marketing, and data analytics technologies. Under the acquisition, AppLovin now manages all MoPub infrastructure, including ad servers and data collection.
What does mopub.com do with data?
As an ad platform, mopub.com is used by app developers to serve ads within their apps. When you use an app that integrates MoPub, the domain may:
- Collect advertising identifiers (such as IDFA on iOS and GAID on Android);
- Record device information like model, OS version, and screen resolution;
- Track your in-app behavior (e.g., sessions, clicks, interactions);
- Serve targeted ads based on this data.
This information is used to display personalized ads and measure campaign effectiveness. MoPub may also share data with partners and advertisers for targeting purposes.
Why block it?
Privacy tools, such as ad blockers and tracking lists, include mopub.com because it is a tracking domain. Blocking it prevents your activities from being monitored for targeted advertising, reducing data collection without your consent.
Limits of DNS blocking
Blocking mopub.com via DNS prevents your device from connecting to that domain. However, keep in mind:
- Does not remove ads served from the same domain as content: if an app loads ads from the same domain as the main content, blocking may fail.
- Does not hide your IP: even if the domain is blocked, your IP address can still be visible to other services.
- May break apps: some apps may not function properly if they cannot load ads or related features.
Final thoughts
Blocking mopub.com helps limit tracking, but it is not a complete privacy solution. A broader approach, like using a robust ad blocker or a service such as Hado99, may offer greater protection, though no tool is perfect.
