Puma creates a `UnixServer` which is a ruby stdlib class, using the defaults, which is extending `UnixSocket` which is also using the defaults
https://github.com/puma/puma/blob/fba741b91780224a1db1c45664...
Those defaults are creating a socket of type `SOCK_STREAM`, which is a tcp socket
> SOCK_STREAM will create a stream socket. A stream socket provides a reliable, bidirectional, and connection-oriented communication channel between two processes. Data are carried using the Transmission Control Protocol (TCP).
