Dear Address working Group IN RIPE NCC Congratulation to you for new year. there are important questions about PA assignment addresses to a customer. If a customer have a black PA IPV4 addresses (f.e: /22) from one lir with specified ASN which has been routed though it,and decide to reroute it from another ASs is it possible?IN fact there are 2 situation: 1.this customer have a block of PA IPV4 from LIR1 with ASn1 and route it.Simultaneously the customer decide to reroute it from another internet provider (ASn2).Is it possible?what policies are considered to RIPE and LIR1?weather the customer need to get agreement with LIR1?HOW? 2.The customer decide to disconnect internet link from LIR1 and connect through another ASN but have preferred to hold PA addresses from LIR1 and route it from another provider and new provider has accepted to route LIR1 PA addresses.Is it possible reroute it without renumbering?and weather RIPE NCC agree to this matter ?if it need to agreement with LIR1 ,what policie are considered by LIR1 and their customer? Many thanks to explain clarify this matter. The best regards.
