When a page I wanted today wouldn't load, I got it to load by disabling IPv6 per Mozilla's instructions at https://support.mozilla.org/en-US/kb/fi ... owsers-can. In recent months I have occasionally encountered similar blank pages, which then I ignored. I am now presented with the choice of whether or not to reenable IPv6; and I'm therefore asking: What exactly do I gain by keeping IPv6?

In answer to your question, not sure.

Though you can set specific domains to use IPv4 instead of 6.


The pref, network.dns.ipv4OnlyDomains, string type, & then the domains needed, like, dslreports.com.
Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.1.19) Gecko/20110420 SeaMonkey/2.0.14 Pinball CopyURL+ FetchTextURL FlashGot NoScript

Thanks, therube.

Before implementing your suggestion, I did a bit of research on my own and found the following listed benefits of IPv6:

    No more NAT (Network Address Translation)
    Auto-configuration
    No more private address collisions
    Better multicast routing
    Simpler header format
    Simplified, more efficient routing
    True quality of service (QoS), also called "flow labeling"
    Built-in authentication and privacy support
    Flexible options and extensions
    Easier administration (say good-bye to DHCP)
This explanation is a bit too sophisticated for me. Perhaps someone can interpret it as applied to the user [me].

all do not apply on firefox.
leave ipv6 in firefox enabled (default) as long you dont run in trouble or your network cant work on ipv6 (given by provider)

I appreciate the advice to keep IPv6, although it seems a bit strange that you folks who advise it can't seem to say why. In any case I have reenabled it, and (though I'm not certain that the IPv is the cause) doing so seems to have cleared up some minor problems I was having.

i can not give you a reason, not savvy enough. i know that windows 10 need ipv6 for its internal work flow thus it is enabled and my provider offers it (my router). so i enabled it in firefox again (long time usage ipv4 with windows 7/8) and had no negative impact until now. if your network dont offer ipv6 then it does not matter if enabled or not, but it can cause nifties when i remember voices here.

IPV6 is the next generation of IP addresses and as such you need it as more and more of the new addresses get taken up.
see
https://en.wikipedia.org/wiki/IPv6
I think from memory the last batch of IPV4 addresses had pretty much been exhausted a fair few years ago
Edit :Yep
https://en.wikipedia.org/wiki/IPv6#IPv4 ... exhaustion
Glad I am not in networking class doing IPV6 subnet masks :shock:

Not really, I think there's still about 10% free IPV4 address space available, to see this you'd actually need to fetch the iprange_ipv4_bogons report and take a glance through it.
