Your public IP address, via Google Search

That's really good. Nice to see some innovation in SERPs - it lists ingredients that go in/with, for example, gazpacho and you can choose to include or exclude them from your recipe search. You can also set cooking times, eg "less than 15 mins"; and set calorific values, eg "less than 300cal".

Interesting, it'll display -0.345756 as the answer, but if you toggle the radians/degrees switch twice, it'll show you -0.3457564464

Yes, I believe so. I often use google for quick calculations and this is the first time I am seeing this show up.

Or a 3d plotter: https://www.google.com/search?q=ln(x)%20-%20sqrt(y)

It has - this is very old news http://news.ycombinator.com/item?id=3128665

That's nice. The website seems to have a special case for when your browser-string is curl?

I like http://jsonip.com/ as well

I like http://icanhazip.com best

It would be nice if there was a switch or param that we could use with Google's IP query to make it only return a minimal response on the page, or perhaps even get the IP via a HEAD request.

Some applications need to use the public IP address. So far we mostly have to maintain our own solutions (http://myip.wampdeveloper.com/) for our own products (http://www.devside.net/server/webdeveloper).

I got excited about GoogGoogle's IP query, then I looked at the page's source code! I guess I could parse that but still, there is no guarantee the format/syntax/text would stay the same.

So far I've seen a few dozen different IP return URLs. And I'm sure there are 1000s more private ones. If we could have one that's guaranteed to be around, that would help everyone out.

You didn't give a reason why you prefer duckduckgo, or why anybody else should. (I'm using that engine myself.)

It works with the &hl=en parameter. I'm using a Swedish VPN so I ran into the same problem.

This is what I got when I clicked on the HN link:

Your public IP address is 2001:610:1908:8000:224:1dff:----:---

Keep in mind that although you might think you're on ipv6, there's a lot of stuff between you and google that might prevent you from actually connecting to google using ipv6.

I'm on a university campus that explicitly negotiated with google to have us on their ipv6 whitelist pretty early on. I forgot why they had a whitelist, hopefully its easier getting on google through ipv6 now.

edit: redacted a bit, I just realised maybe publishing my ip could have negative effects

WFM, I see "Your public IP address is 2620:0:1042:1:...."
