     1.9 +
    1.10 +The gethostbyname4() lookup method is problematic since it fires out both
    1.11 +the A and AAAA DNS queries in parallel and over the same socket. This
    1.12 +should work in theory, but it turns out that many cheap DSL modems and
    1.13 +similar devices have buggy DNS servers - if the AAAA query arrives too
    1.14 +quickly after the A query, the server will generate only a single reply
    1.15 +with the A query id but returning an error for the AAAA query; we get
    1.16 +stuck waiting for the second reply.
    1.17 +
    1.18 +For gethostbyname4() users affected, disabling IPv6 in the system might
    1.19 +work around the issue, unfortunately it only helps with applications
    1.20 +using AI_ADDRCONFIG (e.g. Firefox); some (notably e.g. Pidgin) neglect
    1.21 +to do that.
    1.22 +
    1.23 +Real fix should be using separate ports for the A and AAAA queries.
