Get IP Address from Command Line

By  on  

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.

    Unicode CSS Classes

    CSS class name structure and consistency is really important; some developers camelcase classnames, others use dashes, and others use underscores.  One thing I've learned when toying around by HTML and CSS class names is that you can actually use unicode symbols and icons as classnames.

Discussion

  1. ifconfig | grep mask
    
  2. ElanMan

    I prefer the slightly simpler/easier to remember

    curl ifconfig.me
    
  3. nedt

    ipinfo.io can give you even more information and is easier to use via tunneling as it works without a host header.

  4. MaxArt

    Windows users can use ipconfig (notice the ‘p’).

  5. Your internal IP also depends on interface you’re using, in your case (en0) it was ethernet, but it also can be WiFi (en1).

  6. ip route get 8.8.8.8 | awk 'NR==1 {print $NF}'
  7. Some time ago I started using an alternative which only uses DNS queries:

    dig +short myip.opendns.com @resolver1.opendns.com
  8. Google > “My IP” = Winner!

  9. $ 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

  10. I just search Google for “what is my ip” like a n00b.

  11. 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'"
  12. hahaha, i just think to google it :D, but thanks dude, sometimes need to apply to my terminal command

  13. 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"
