Get IP Address from Command Line
Over the past few years I've needed to look up my IP address a dozen times. What's funny is that I don't recall why I needed it, I just did. So what's the easiest way to get my IP address from the command line?
To get your internal IP, you can do the following:
ipconfig getifaddr en0
I go through ipecho.net to get it:
curl ipecho.net/plain ; echo
# >> 71.87.32.78
Why go through an external resource? Your local address and your external address aren't the same, so using the external resource is the best way to tell what the world is seeing your IP address as.
![How I Stopped WordPress Comment Spam]()
I love almost every part of being a tech blogger: learning, preaching, bantering, researching. The one part about blogging that I absolutely loathe: dealing with SPAM comments. For the past two years, my blog has registered 8,000+ SPAM comments per day. PER DAY. Bloating my database...

Kids these days, I tell ya. All they care about is the technology. The video games. The bottled water. Oh, and the texting, always the texting. Back in my day, all we had was...OK, I had all of these things too. But I still don't get...

As much as developers now loathe Flash, we're still playing a bit of catch up to natively duplicate the animation capabilities that Adobe's old technology provided us. Of course we have canvas, an awesome technology, one which I highlighted 9 mind-blowing demos. Another technology available...
![Fading Links Using jQuery: dwFadingLinks]()
UPDATE: The jQuery website was down today which caused some issues with my example. I've made everything local and now the example works.
Earlier this week, I posted a MooTools script that faded links to and from a color during the mouseover and mouseout events.
I prefer the slightly simpler/easier to remember
ipinfo.io can give you even more information and is easier to use via tunneling as it works without a host header.
Windows users can use
ipconfig(notice the ‘p’).Your internal IP also depends on interface you’re using, in your case (en0) it was ethernet, but it also can be WiFi (en1).
ip route get 8.8.8.8 | awk 'NR==1 {print $NF}'Some time ago I started using an alternative which only uses DNS queries:
Google > “My IP” = Winner!
$ curl ipinfo.io { "ip": "174.47.27.98", "hostname": "174-47-27-98.static.twtelecom.net", "city": "Orange", "region": "California", "country": "US", "loc": "33.7878,-117.8531", "org": "AS4323 tw telecom holdings, inc.", "postal": "92666" } $ curl ipinfo.io/ip 69.170.45.10 $ curl ipinfo.io/org AS4323 tw telecom holdings, inc.See http://ipinfo.io/developers for more details
I just search Google for “what is my ip” like a n00b.
I prefer:
alias publicip='curl ipecho.net/plain ; echo' alias localip="ifconfig | grep -Eo 'inet (addr:)?([0-9]*\.){3}[0-9]*' | grep -Eo '([0-9]*\.){3}[0-9]*' | grep -v '127.0.0.1'"hahaha, i just think to google it :D, but thanks dude, sometimes need to apply to my terminal command
It is ugly. But the Google lovers will enjoy.
Prerequisite: curl, and grep.
curl -s "https://www.google.ie/search?client=firefox-b&q=myip&oq=myip&gs_l" | grep "Client IP address" | grep -oE "\b([0-9]{1,3}\.){3}[0-9]{1,3}\b"
