## happy eyeballs -- connecting to a remote host
|
||
|
|
|
||
|
|
[RFC 8305](https://datatracker.ietf.org/doc/html/rfc8305) describes how to
|
||
|
|
connect to a remote host, given that the host may have multiple addresses (IPv4
|
||
|
|
and IPv6, via DNS A and AAAA resource records), and the local host may have
|
||
|
|
connectivity via IPv4 only, IPv6 only, or both. The preference is to use IPv6.
|
||
|
|
|
||
|
|
This package implements the given RFC in its core (Happy_eyeballs module).
|
||
|
|
In addition, the Happy_eyeballs_lwt is a Lwt implementation using Unix.
|
||
|
|
|
||
|
|
The implemented [state machine](https://data.robur.coop/happy_eyeballs.pdf) is
|
||
|
|
kept in-sync with the code (source: happy_eyeballs.dot at the root of this
|
||
|
|
repository).
