About the AS205941 network
A personal, IPv6-first autonomous system operated by Ștefan-Gabriel Lungu (LSG). Runs BGP across multiple upstreams and European internet exchanges, dual-stack everywhere, and hosts DNS, mail, monitoring, and a handful of side projects.
AS205941 is a personal autonomous system operated as a serious, production-grade network. It exists to learn, to build, and to contribute back to the routing community — running the same tooling and rigor you'd expect from a commercial operator, at a scale one person can maintain.
The network is IPv6-first and dual-stacked end to end, present at multiple internet exchanges with an open peering policy. All announcements are RPKI-valid, IRR-registered, and consistent across every exchange. We participate in MANRS and treat routing security as a baseline, not a feature.
Everything here runs on realistic data today and is designed to swap to live infrastructure without changing a single screen — the same philosophy of clean interfaces and honest signals that guides how the network itself is run.

Principles
IPv6-first
IPv6 is the default; IPv4 is the fallback. Every service is dual-stacked and reachable over v6.
Routing security
RPKI ROAs on every prefix, strict IRR filtering, and MANRS conformance — no exceptions.
Automation over toil
Router config is generated from a single source of truth. No hand-edited BGP.
Open by default
Open peering, public looking glass, transparent status, and open-source tooling.
