Dear Mehdi,

You can read more about the Resource Certification (RPKI) project here:

http://ripe.net/certification

The message you received was about which types of IP address blocks are eligible to be used with the certification service. You can find a full overview of all eligible space in this FAQ entry:

http://www.ripe.net/lir-services/resource-management/faq/certification/i-dont-see-one-of-my-address-blocks-on-my-certificate.-why-is-that

Please do not hesitate to contact me if you have any questions.

Kind regards,

Alex Band

I was dubious are you the right section to ask me my question or not but since i have not found any other email linked to RIPE i had to email you .Just wondering do you know any information about (PI and Anycast space marked as INFRA eligible for Resource Certification (RPKI)) and what do we have to do? otherwise mind  me to the right section or contact person which I can enquire in this regard.
I am looking forward your prompt response.
