Florian Bauer (AS210833) is a small, personally operated IPv6 network in Germany that peers at three exchanges and announces two /48 prefixes. Public evidence confirms the registry and routing footprint but leaves the legal, financial, and biographical dimensions undefined. Watchpoints include registry changes, prefix reachability, and peering status updates. The network's open peering policy and stable prefix announcements make it a useful benchmark for small-scale IPv6 monitoring, though its overall impact is limited by its niche scope.
AS210833 is a personally operated IPv6 autonomous system in Germany, publicly listed as Florian Bauer/FSRV. The operator holds a RIPE LIR designation and manages RPKI-signed prefixes, IRR policies, BGP sessions through three upstreams, and public peering at EVIX, KleyReX, and LOCIX DÜSSELDORF. The control surface is limited to these registry and routing configurations.
AS210833 introduces a measurable dependency point for European IPv6 traffic via its two announced prefixes and open peering policy. Changes in prefix reachability, upstream connectivity, or exchange participation can disrupt services and end-users that rely on the FSRV-labelled address space. Monitoring is necessary for accurate infrastructure dependency mapping.

Several public sources
Florian Bauer
Florian Bauer operates AS210833, a small personal IPv6 network in Germany that peers at three internet exchanges and announces two /48 prefixes. The network’s public footprint is documented in RIPE, PeeringDB, and routing datasets, but its commercial, legal, and personnel dimensions remain unexplored. It creates a measurable, niche dependency in European IPv6 routing that warrants monitoring for infrastructure mappers.
Why It Matters
If AS210833 were to withdraw its prefixes, alter its upstreams, or change its peering configuration without notice, downstream IPv6-dependent systems could experience partial or total loss of connectivity to the announced address space. The disruption would ripple through local exchange participants and any network transiting those upstreams or IXs, altering the routing picture for a niche segment of the internet.
What Public Sources Show
Florian Bauer operates AS210833, a small but measurable IPv6 network in Germany. It announces two /48 prefixes and maintains an open peering policy at three regional internet exchanges. While its overall footprint is modest, it introduces a concrete dependency point for European IPv6 traffic that warrants monitoring.
RIPE registry records identify the operator as Florian Bauer, also listed under the alias FSRV. The autonomous system has been active since August 2021 and carries the designation of a Local Internet Registry. Its two announced prefixes are 2001:67c:828::/48 (primary infrastructure) and 2a05:d4c0:ffff::/48 (lab network).
Public routing data shows AS210833 peers at EVIX, KleyReX, and LOCIX DÜSSELDORF. It uses upstream transit from AS20473, AS34872, and AS34927. Both prefixes are covered by valid RPKI origin authorizations, and the operator publishes an IRR routing policy as AS-FLORIANBAUER.
Changes to the network's prefix announcements, peering, or upstream connectivity can disrupt IPv6 reachability for the FSRV-labelled address space. Since the network offers open peering, local exchange participants and any networks transiting those upstreams or IXs may experience partial or total loss of connectivity to these prefixes.
The evidence is limited to registry and routing sources. The operator's website, as210833.net, has not been reviewed, and no corporate registration or commercial services are documented. The legal and financial structure of the operation remains unknown, as does the individual's broader professional background.
Watchpoints include any modifications to the RIPE aut-num or organisation records, withdrawal of the announced prefixes, changes in upstream transit or IX peering status, and publication of commercial services. These signals would alter the network's dependency relevance and require re-assessment of its role in the local peering ecosystem.
Operating Surface
AS210833 is a personally operated IPv6 autonomous system in Germany, publicly listed as Florian Bauer/FSRV. The operator holds a RIPE LIR designation and manages RPKI-signed prefixes, IRR policies, BGP sessions through three upstreams, and public peering at EVIX, KleyReX, and LOCIX DÜSSELDORF. The control surface is limited to these registry and routing configurations.
AS210833 introduces a measurable dependency point for European IPv6 traffic via its two announced prefixes and open peering policy. Changes in prefix reachability, upstream connectivity, or exchange participation can disrupt services and end-users that rely on the FSRV-labelled address space. Monitoring is necessary for accurate infrastructure dependency mapping.
Watchpoints
AS210833 represents a personally operated, low-overhead IPv6 network that nevertheless maintains a disciplined routing presence with RPKI and IRR coverage. Its open peering policy makes it a useful benchmark for small-scale IPv6 monitoring, but its dependency impact is limited by its scale and the absence of known downstream services.
Registry changes (aut-num, organisation, as-name), prefix withdrawals, upstream or IX peering changes, and the appearance of commercial services would alter the risk surface.
Missing: website content review, corporate registration, customer contracts, personal biography, and exact peer/upstream snapshots. These would strengthen dependency mapping and reveal whether the network is a hobby, lab, or commercial service.
