+welcome to le-fay.dn42, AS4242421495.
+
+[overview]
+== overview
+
+* ASN: 4242421495
+* location: UK
+* contact: ft.dn42@le-fay.org
+* networks:
+** fd5b:a83:b06b::/48
+** 172.23.76.0/26
+
+[peering]
+== peering
+
+i am accepting peerings in the UK & Ireland.
+please see the link:nodes/[list of nodes] for information about nodes
+accepting new peerings.
+all nodes support multiprotocol BGP with extended next hop for IPv4 prefixes;
+BGP itself is only supported over link-local IPv6 addresses.
+
+peering requests with an excessively high rtt may be rejected to preserve
+network quality.
+
+to request a peering, please mail ft.dn42@le-fay.org and include:
+
+* the node you want to peer with
+* your DN42 ASN
+* your Wireguard endpoint address, port, and public key
+* your BGP link-local address
+* whether you want IPv4 routes, IPv6 routes, or both
+	(note that in any case, BGP peerings are always over IPv6 link local
+	addresses)
+
+[communities]
+== BGP communities
+
+routes advertised by AS4242421495 may have one or more of the following
+communities attached:

+|===
+
+[.red]#*# - these communities should never be seen on DN42
+
+the node-specific and region-specific communities are only attached when the
+route is originated or received from an external peer.  for example, a route
+tagged with 4242421495:2:1 was either received by rose from an external EBGP
+peer, or was locally originated on that node.  therefore, any route should only
+have a single node-specific and region-specific community.
