 #### Limitations of relay nodes:
 - v2 relays are "limited relays" that are designed to be used for [Direct Connection Upgrade through Relay](https://github.com/libp2p/specs/blob/master/relay/DCUtR.md) (aka hole punching).

 ## Implementations
 
-Protocol Labs manages two implementations of the IPFS spec: Kubo and Helia. These implementations use specific types of _nodes_ to perform server, browser, and other client functions.
