Free IP transit over tunnels
Verify your ASN, create a tunnel and bring up BGP sessions. Free for approved networks, best-effort and without an SLA.

- SIT
- VXLAN
- WireGuard
Free because of our sponsors
bgp43 runs on routers, rack space and transit donated by these networks. They make free transit possible - say thanks by checking them out.
All sponsorsNetwork tools and policy
- Looking GlassQuery BIRD on bgp43 edge routers live: look up routes, inspect BGP sessions, ping and trace from each location.
- StatusService status for bgp43.
- Peeringbgp43 has an open peering policy for networks that want settlement-free BGP peering over a dedicated tunnel or at an IXP where bgp43 is already connected. We do not provide tunnel access into an IXP fabric.
- CommunitiesUse these communities to narrow route export or request AS-path prepend, and read the source tags bgp43 adds to every route it learns.
Transit for ASNs that need a clean start
bgp43 is built for small operators, labs and network projects with a valid ASN. No sales flow and no uptime promise: just reviewed access, tunnels and a practical dashboard.
- Free after approval
- Submit your ASN, prove ownership and wait for manual review. After approval, tunnel and BGP controls unlock.
- Tunnel before BGP
- GRE, SIT, VXLAN or WireGuard tunnels are created in the dashboard. BGP sessions attach to a ready tunnel.
- Filters at the edge
- ASN ownership, public contacts, RPKI/IRR signals and suspicious announcements are checked to keep routing predictable.
- BYOIP by request
- Before submitting a BYOIP request, the prefix must already have IRR and RPKI objects on ASN 197324. Then submit the prefix, pass strict validation, and create a tunnel for static routing or a BYOIP BGP session.
- Honest best-effort
- This is community infrastructure without an SLA. Maintenance, abuse response and upstream changes can affect availability.
Three steps to your first BGP session
Add your ASN
Create an account and send the verification code from a public RIR/WHOIS contact.
Create a tunnel
After approval, choose a router and tunnel type. The dashboard shows inside addresses and parameters.
Bring up BGP
Create IPv4/IPv6 sessions, keep announcements clean and watch the status in the dashboard.
What approval requires
The rules are short: own the ASN, announce only authorized prefixes and do not use the service for abuse.
- Use a valid ASN with a reachable contact email.
- Confirm ASN ownership from the registry contact.
- Announce only prefixes you are authorized to route.
- BYOIP prefixes require exact valid IRR and RPKI objects on ASN 197324 before the request is submitted and before review.
- Keep traffic lawful and within fair usage.
- Abuse, spam, scanning and unclear routing intent are rejected.
Start with ASN verification
The dashboard walks you through contact check, review, tunnels and BGP. The fastest path starts with your ASN.
