+## Workarounds
+
+### Network address family autoselection.
+
+If you experience problem when connecting to a remote server that is resolved by your DNS servers to a IPv6 (AAAA record)
+first, there are chances that your local router or ISP might have problem connecting to IPv6 networks. In that case
+undici will throw an error with code `UND_ERR_CONNECT_TIMEOUT`. 
+
+If the target server resolves to both a IPv6 and IPv4 (A records) address and you are using a compatible Node version 
+(18.3.0 and above), you can fix the problem by providing the `autoSelectFamily` option (support by both `undici.request`
+and `undici.Agent`) which will enable the family autoselection algorithm when establishing the connection.
