Techopedia Explains Tunnel Broker

Tunnel brokers such as IVI, TRT and others vary in terms of regions, subnets, tunnel protocols supported, etc. IPv4 and IPv6 tunnel brokers help to facilitate tunnels in either of these IP protocols. The tunnel broker service often involves encapsulating data and changing the structure of data to shield it from outside interference or viewing. Tunnel broker services are always evolving as enterprise and other systems use the global internet as an increasingly universal route for data.
