Hello everyone. We're migrating a legacy network to IPv6 over the next year but need extra IPv4 capacity during the transition, maybe six months. Buying feels wasteful for that. Are there short leases, or do brokers only want multi-year deals? Also, how do you handle the LOA and announcement side? We have about forty racks of old gear that won't speak IPv6 until we replace it, so IPv4 is unavoidable for now. The CFO wants to see a clear exit plan before approving anything. Time is tight.
