FIOS users waiting for IPv6... script to let you know when it's ready

[luckman212]

So for anyone who hasn't heard, after almost a decade of waiting, Verizon has started rolling out native IPv6 (dual stack) to their residential FIOS customers. There's a discussion over on the DSLReports forum.

I'm excited about this- but got tired of testing my connection every couple of days to see if V6 was available. I threw this simple script together which should send an email alert once the RAs start appearing on the WAN interface. Posting here in case anyone else might find it useful.

How are they (finally) provisioning it?

I don't have it (yet) but I hear they are allocating a /56 via DHCPv6-PD.

I was seeing RAs on Rogers long before they offered IPv6. When I examined the packets, they were missing minor details like defaut gateway.

Small update:

I rewrote the script in PHP and it now accepts a parameter to specify the interface you want to check, which is more flexible.

<?php

  include("notices.inc");

  if (!empty($argv[1])) {
    $if = $argv[1];
  } else {
    $if = "igb0";
  }

  exec("/sbin/rtsol -DF $if 2>&1", $result, $retval);
  if (($retval == 0) && (count($result))) {
    $haystack = implode("\n", $result);
    $needle = "received RA from [a-f0-9:\.]+ on $if";
    preg_match("/$needle/", $haystack, $matches);
    if (count($matches)) {
      $msg = "IPv6 RAs detected on interface $if";
      notify_via_smtp($msg);
    }
  }

?>

Any dhcp6-pd packet captures from the G1100? I am having trouble determining the correct advanced DHCP6 settings for pfSense
