Dualstack Networking


Support proper dual stack networking. All major system services and user applications should work with both IPv4 and IPv6. All of them should also be able to cope with multiple addresses per hostname via proper use of getaddrinfo().


Current status

Detailed description

Fedora supports dualstack global networking. That means the computer with Fedora is connected to internet using both IPv4 and IPv6 protocols. But many important system services and applications either don't do IPv6, do it incorrectly, or don't cope with various network conditions.

Dualstack-ready software must cope with all possible scenarios including IPv4-only connectivity, IPv6-only connectivity and dualstack scenarios. The software must also cope with node-local (aka localhost) networking.

Though it would be nice to have all applications in Fedora fixed to work in any of the scenarios, it is not feasible to test that. Therefore this bug report is about major software used in servers, desktops and laptops. The list of such applications will be completed over the time.


  • glibc: name resolution must work properly
  • glib: provides networking API for applications

System services

  • knfsd
