TANGLED was conceived in 2016, during a BGP hackathon organized by CAIDA/UCSD. The first release of the TANGLED was presented during RIPE73 meeting. In the following years, we expanded the testbed, deploying anycast sites around the world.

The anycast research testbed has been created within the context of DACS, a consortium consisting of the University of Twente, SIDN Labs, NLnet Labs and SURFnet.

Address prefixes and ASN resources have been allocated by SURFnet and RIPE NCC.

IPv4: 145.100.118.0/23
IPv6: 2001:610:9000::/40
ASN 1149


The testbed currently in expansion and already has several locations either operational or being installed.



Some other institutions are supporting our deployments:
We are also thankful to Nat Morris and John Heidemann for their support.
