Restricting the Acquisition of Additional LIR Accounts

29 Settembre 2026 ore 15:55
The RIPE NCC Executive Board has decided to temporarily restrict members' ability to acquire additional Local Internet Registry (LIR) accounts. Taking effect on Tuesday, 29 September, the restriction also covers requests already in progress. The decision is a first step towards addressing the administrative burden of multiple accounts, while allowing related questions about IPv4 allocations from the IPv4 Waiting List to be discussed within the RIPE community.

There is a subtle asymmetry in IPv6 Neighbour Discovery: a host knows how to reach its router before the router necessarily knows how to reach the host. GRAND fixes that asymmetry by making the host proactively advertise its address, and I implemented that mechanism in FreeBSD.

Traceroute is a powerful tool for uncovering how packets travel across the Internet. However, as we recently discovered, some routers tamper with the TTL values in traceroute's probing packets, giving you a false view of how networks are actually interconnected.

Third-party ROUTE(6) objects can largely be phased out, while third-party AS-SETs remain essential for BGP filter generation.
