 ## Connection limits
 
-It's possible to limit the total amount of connections a node is able to make (combining incoming and outgoing). When this limit is reached and an attempt to open a new connection is made, existing connections may be closed to make room for the new connection (see [Closing connections][#closing-connections]).

 - Note: there currently isn't a way to specify different limits for incoming vs. outgoing. Connection limits are applied across both incoming and outgoing connections combined. There is a backlog item for this [here](https://github.com/libp2p/js-libp2p/issues/1508).
