AS212900 is a research and educational AS (Autonomous System), managed by Dr. Pere Tuset-Peiró and located in Barcelona (Spain). Please take your time to browse through the different sections of the website to understand why AS212900 was created, what is the current status of the AS212900 network, and how to peer with AS212900 in case you are interested. However, please notice that due to the lack of IPv4 address blocks, AS212900 is currently an IPv6-only network. Also, be aware that currently peering with AS212900 can only be done with 6in4 or GRE tunnels over the Internet (i.e., IPv4). In the future, we plan to be present in a datacenter or IXP (Internet Exchange Point), where peering can be done through a physical port.
