What’s Flip Flap Network
AS4242420263, aka Flip Flap Network, is my own experimental network on dn42.
dn42 is a decentralized network mainly used as a testbed, it employs common networking protocols (such as BGP, DNS, WHOIS) to reproduce an Internet-like network.
Most network links are configured using VPN tunnels (WireGuard) over the Internet, as such dn42 is an overlay network.

Peering
Policy
Flip Flap Network is open to all peering requests. Each peering systematically uses:
- Wireguard for establishing the peering link
- Link-local IPv6 on each peering link
- Multiprotocol BGP over IPv6
- Extended next hop over IPv6
Auto-peering self-service
You can request a peering session with the nodes below via SSH on port 4242 (provided that your mntner object in the dn42 registry contains at least one auth attribute with a ssh public key of type ssh-ed25519 or ssh-rsa).
In the following commands, replace <mntner> by your maintainer object name, lowercase, without the -MNT suffix.
| Nodes | SSH command | IPv6 | IPv4 |
|---|---|---|---|
nl-ams2.flap42.eu | ssh <mntner>@nl-ams2.flap42.eu -p 4242 | Y | Partial |
fr-par1.flap42.eu | ssh <mntner>@fr-par1.flap42.eu -p 4242 | Y | N |
pl-waw1.flap42.eu | ssh <mntner>@pl-waw1.flap42.eu -p 4242 | Y | N |
us-nyc1.flap42.eu | ssh <mntner>@us-nyc1.flap42.eu -p 4242 | Y | N |
de-fra1.flap42.eu | ssh <mntner>@de-fra1.flap42.eu -p 4242 | Y | N |
ca-yto1.flap42.eu | ssh <mntner>@ca-yto1.flap42.eu -p 4242 | Y | N |
nl-ams2.flap42.eu has outbound-only connectivity to IPv4 endpoints due to NAT (it can reach you, but you cannot reach it directly).
IPv6 is natively supported on all nodes.
Manual request
Peering requests on nl-ams1.flap42.eu are handled manually so specific settings requests are accepted.
This node supports IPv4 and IPv6 natively.
Contact me at <hyacinthe@cartiaux.net>, with the following information:
- AS number
- Wireguard public key
- IPv6 endpoint address
- IPv6 endpoint port
- link-local IPv6 address
Support
I can be contacted by mail <hyacinthe@cartiaux.net> or matrix <@hyacinthe:bsd.cafe>.
