Hello dear lady/sir I am one of your subscriber and first of all appreciate for your help couple of time ago to figure out my problem. 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. Kind regard Mehdi
