[routing-wg] Prefix hijacking possibility

Hi Amer,

In order to help mitigate route hijacking issues, it is considered good practice to register your announcements as route objects in an Internet Routing Registry such as the RIPE Database. This allows other to base routing decisions on them, using filters.

A new alternative is the RIPE NCC Resource Certification service, which was launched at the beginning of this year. This allows you to get a digital certificate for your IP address blocks and create Route Origin Authorisation (ROA) objects, which essentially state "From this Autonomous System, I shall announce these prefixes". This allows anyone on the Internet to *validate* if a certain route announcement has a valid ROA associated with it, created by the legitimate holder of the address space.

You can find more information here: http://ripe.net/certification
And here is a quick-tour: http://youtu.be/Q0C0kEYa1d8

Kind regards,
