Comprehensive guides and articles about ASN registration, IP resources, inter-RIR transfers, and LIR management.
Year, country and IPv6 tables recomputed from the RIPE NCC delegation file of 24 September 2026, with the sponsored share of new ASNs and the method to reproduce every figure.
A ROA names the AS allowed to originate your prefix, and networks running route origin validation drop announcements that contradict it. What a ROA holds, where maxLength goes wrong, and who signs yours under our sponsorship.
Where ROAs are created for LIR allocations and for PI blocks, and why a maxLength wider than the prefix hands a hijacker a valid route.
How transit providers and IXPs turn route objects and as-sets into prefix filters, what the RIPE Database checks before it accepts one, and where a ROA fits beside it.
What an ASPA object contains, which leaks it catches, where the IETF drafts stand in September 2026, and how to sign one without breaking your failover paths.
Where your network is established decides your registry more than price does. What each of the five RIRs charges in 2026, how it hands out IPv4 and ASNs, and which regions can trade addresses.
What IPv4 costs to buy or lease in 2026, where IPv6 adoption stands, and a phased plan that shrinks your IPv4 footprint without breaking production.
