What is MANRS

Mutually Agreed Norms for Routing Security (MANRS) is a global initiative, supported by the Internet Society, that attempts to reduce the most common routing threats.


GR-IX supports MANRS

MANRS requires from Internet Exchange Points to implement the following:

  • Action 1: Prevent propagation of incorrect routing information
  • Action 2: Promote MANRS to the IXP membership
  • Action 3: Protect the peering platform
  • Action 4: Facilitate global operational communication and coordination between network operators
  • Action 5: Provide monitoring and debugging tools to the members

GR-IX adheres to all of the MANRS principles above and considers the role of Internet Exchanges in reinforcing routing security crucial. For that reason, GR-IX supports the MANRS initiative and has joined the MANRS programme since May 2018.

MANRS for Operators

GR-IX strongly encourages its members to join MANRS. MANRS outlines four simple but concrete actions that network operators should take:

  • Filtering – Ensure the correctness of your own announcements and of announcements from your customers to adjacent networks with prefix and AS-path granularity
  • Anti-spoofing – Enable source address validation for at least single-homed stub customer networks, your own end-users, and infrastructure
  • Coordination – Maintain globally accessible up-to-date contact information
  • Global Validation – Publish your data, so others can validate routing information on a global scale
