Network operators have a collective responsibility to ensure a globally robust and secure routing infrastructure. Your network’s safety depends on a routing infrastructure that weeds out bad actors and accidental misconfigurations that wreak havoc on the Internet. The more network operators work together, the fewer incidents there will be, and the less damage they can do.

The MANRS Network Operators Program defines the minimum steps network operators like Internet Service Providers should take to ensure the security and resilience of the Internet’s global routing system.


  1. Filtering. Ensure the correctness of your own announcements and those from your customers to adjacent networks
  2. Anti-spoofing. Enable source address validation for at least single-homed stub customer networks, their own end-users, and infrastructure
  3. Coordination. Maintain globally accessible, up-to-date contact information in common routing databases.
  4. Global information. Publish your data so others can validate
