ipv6 Rated 4 out of 5 stars

when I use the nslookup command in my linx machine I get only ip4 address of domain but your addon shows ipv6 too for some addons . how is that possible?

EDIT:
I said it wrong.
I meant that your addon description says that it doesn't do anything just uses my system provided info to show the ips that I am connecting to for each domain.
but now you are saying that it forces my system dns to also check to see if they have ipv6?

for example I have disabled the ipv6 on my system.
and I use your addon to see which domain uses which ip.and which one is connecting via proxy.( I have a lot of those).


so for each domain that I am connecting you addon makes a ipv6 check via dns?

Edit:

Hi again,

SixOrNot doesn't query an external service to, for example, find out your external IP address or perform DNS queries - but it does make use of your local system's DNS resolution mechanism to perform a DNS query for each domain visited. This is used to display the yellow/blue icons (showing whether IPv6 is available and not being used, or if a site can only be contacted by IPv6). Typically this DNS query is serviced from the local cache (since your web browser will have very recently performed the same query to connect to the page) though in the case of cached pages, or where IPv6 has been disabled it's possible that this will result in additional DNS queries going "across the wire".

The queries are all handled asynchronously by the addon and so shouldn't have any performance impact (especially in the latest multiprocess versions of Firefox with electrolysis enabled). Also, DNS queries are only performed for the "main" domain contacted as a matter of course (this is used to update the main icon UI when the information panel isn't displayed). DNS queries are only performed for the "secondary" domains contacted to load the page when the panel is opened. This was a change from v1 (which did the DNS lookups at the time when the connections were made) which was necessitated by the change in addon architecture to support electrolysis/multiprocess.

(It's also probably worth pointing out that the addon (v2+) doesn't perform DNS resolution for connections that are made via HTTP/HTTPS proxies, or SOCKS proxies where the proxy handles DNS resolution - this is to avoid leaking information about connections made over proxies via DNS queries)

It wouldn't be too hard to provide a preference to disable the DNS resolution feature for your use case though if you're concerned by the extra network traffic. Originally the whole point of this addon was to provide info about IPv6 availability, but I can see that there's a definite use case for just seeing the IP addresses/proxy info/SSL info now. I'll see about adding a preference for the next release and updating the description so it's clearer exactly what the network traffic impact of the addon may be.

Thanks!

Hi there,

nslookup defaults to retrieving A records for a domain (A records are for IPv4 addresses) - you can get nslookup to retrieve AAAA records (the IPv6 equivalent of A records) with the "-query=AAAA" flag - e.g. "nslookup -query=AAAA google.com".

Thanks :)

When used with ClassicThemeRestorer, with the stop/reload button in the location bar removed, the icon that this places in the location bar ends up jammed against the edge of the location bar box.

Otherwise, nice that it's working again with e10s.

Hi David, thanks for your review - I'll have to take a look and see if I can fix that :)

Great! Rated 5 out of 5 stars

I do not use the Fx Dev version right now. However: future regular versions of Fx will have E10s and the developer has added now the support for this already - GREAT!

Not working on Firefox Nightly x64. Can you fix it?
On other Firefox versions, excellent!

I'll look into it, thanks for letting me know - what OS are you seeing the problem on?

Useful for webmasters Rated 5 out of 5 stars

This is a great tool for checking whether CDNs and other dependencies like ad providers and analytics tools are v6-enabled.

Working fine here on 32.0b on OS X 10.9.

Just fine here with Firefox 16.01 Rated 5 out of 5 stars

After having installed protocol 'Microsoft TCP/IP Version 6' from within XP-SP3, even though I remain at this time IPv4 restricted, SixOrNot allows me to discover when a website is "IPv6 ready". Not to mention "information about all the domains contacted in order to load the page" (which is my first motivation). Nice.

This addon is great for displaying the IPv6 status of web sites. It also displays IPv6 info for external resources loaded from the web site.

Works FF v12 Rated 4 out of 5 stars

Better than IPvFox. Needs location info added.

Works nicely Rated 4 out of 5 stars

Fun add-on for IPv6 enthusiasts and useful for techies.
Latest version (v0.6.6) fixes local IPv6 address detection. Now works as described.

Best guess, no actual check Rated 3 out of 5 stars

Not 100% bullet proof: If your host has IPv6 configured and the domain has IPv6 in DNS, but you are unable to connect (IPv6 tunnel issues, etc). This case it does not detect the fallback to IPv4 protocol.

Hi Rick,
Thanks for your feedback. This is definitely a big limitation, I haven't been able to figure out a good way to get around this yet without having the addon actively try to communicate with the domain in question. Something to work on though!
Thanks,
Timothy

Great add-on! Rated 5 out of 5 stars

This is just the thing I was looking for - a simple IPv4/6 indicator, that can be nicely embedded into an address bar.

Hi, i personally don't see a reason for showing the ipv4 only icon in the status bar. As it actually is there like all the time. Would be nice to find an option to disable/hide the status bar indicator complete if there is none of the ipv6 supported states found.

Working fine, even on Nightly: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:7.0a1) Gecko/20110613 Firefox/7.0a1

very nice! Rated 5 out of 5 stars

A brilliant idea! I love this addon already. I dragged the icon next to my URL Bar so i can see in 1 eye if i connect through IPv6 or ipv4 ! excellent job!.

Nice! Rated 5 out of 5 stars

It works nicely. The toolbar icon is small but elegant, and it provides the right detailed information with a single click. Perfect for testing on World IPv6 day! (and beyond)
