YSK how to get your IP address from the command line (gekinzuku.com)

While it's easy to get an IP address from popular websites such as whatismyip.com, it's not often friendly to a context where you might need to get your IP address for command line tools.

In order to grab your IP address via the command line, there's a page on a site called ipinfo.io/ip which only contains body content corresponding to your IP address. The easiest way to fetch that data is with the curl command (should be available on both Windows and Linux).

curl ipinfo.io/ip

It may also be beneficial to add this to your .bashrc or .aliasrc on Linux systems with something like

alias myip="curl ipinfo.io/ip"

Now you have an easy way to grab your IP address from the command line!

curl --silent https://myipv4.p1.opendns.com/get_my_ip | jq --raw-output '.ip'
curl --silent https://eth0.me
curl --silent https://ifconfig.me/ip
curl --silent https://ipecho.net/plain
curl --silent https://ipinfo.io/ip
dig @resolver4.opendns.com myip.opendns.com +short

That last one is generally much faster than the rest.

Also, you can add -w '\n' to curl commands to make it add a newline.

I like to be sworn at in json:

curl myip.wtf/json

curl ifconfig.io works too

[–] xebix@lemmy.world 3 points 1 year ago

ipify.org is yet another.

curl https://api.ipify.org

You can also use curl "https://eth0.me"

[–] graham1@gekinzuku.com 2 points 1 year ago (1 children)

Nice! That's a good short one as well, and I wasn't aware of it before.

[–] housepanther@lemmy.goblackcat.com 2 points 1 year ago

I accidentally found it while I was looking for something completely unrelated and it just stuck in my mind. 😹

% curl ipinfo.io/ip
curl: (7) Failed to connect to ipinfo.io port 80 after 25 ms: Connection refused
% curl https://ipinfo.io/ip
curl: (7) Failed to connect to ipinfo.io port 443 after 29 ms: Connection refused

They suck and apparently block curl (and lynx and elinks) from dynamic IP, it works in Firefox or on a server with static IP.

Another one is ifconfig.me/ip so

curl https://ifconfig.me/ip

that works.

[–] graham1@gekinzuku.com 2 points 1 year ago

Oh I had no clue they block curl from a dynamic IP. That's a good alternative to have!

[–] Max_P@lemmy.max-p.me 2 points 1 year ago

Another one: curlmyip.net

[–] JoeClu@lemmy.world 2 points 1 year ago (1 children)

Is 'ifconfig -all' no longer a thing?

[–] graham1@gekinzuku.com 2 points 1 year ago (1 children)

If you're connected to the internet via a local network such as a router or modem, ifconfig will give your local IP address, not your public IP address. Instead, the methods in this post and comments all discuss ways to get your public IP address. It usually requires contacting an external server that you trust and asking them "which IP address did I just contact you with?"

[–] JoeClu@lemmy.world 2 points 1 year ago

Thank you for being kind in explaining that to me.
