DFOH

A System to Detect Forged-Origin BGP Hijacks

We report new AS links in near real time (with a five-minutes delay) and observed within the last 24 hours.
We highlight the suspicious cases in red. You can click on a row in the table to see more details about a particular case.
For the live version, we only run DFOH with a confidence level of one and only use RIPE RIS data.

You can use the form below to apply filters on the listed cases.


We found 219 new AS links during the last 24 hours among which 22 are suspicious.
