I recently deployed a droplet on vultr and i need to find the external and internal IP addresses. I have just one IP (which i presume to be the external IP or not). How and/or where do i locate the two IPs? The server is running on ubuntu

  • ifconfig is your friend, that is, when Ubuntu runs on ...some hardware. – mikewhatever Jun 25 at 22:02
  • I would likely use ip addr (esp. if ifconfig is not installed) – guiverc Jun 25 at 22:56

There's a simple command to get all IP info, and it tells you if it's local (internal) or global (external)

Just run:

sudo ifconfig

And presto, you'll know all you wanted to and more

To get your internet (WAN) IP address: wget -qO- ifconfig.me/ip

To get your internal (LAN) ip address(es): ip addr | grep inet

1

From the command prompt, to find your internal IP address:

ip addr show

You may get a result something like:

3: wlp3s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    link/ether 5c:c5:d4:0e:64:a6 brd ff:ff:ff:ff:ff:ff
    inet 192.168.0.11/24 brd 192.168.0.255 scope global dynamic noprefixroute wlp3s0
       valid_lft 172442sec preferred_lft 172442sec
    inet6 2600:1700:xxxx:83d:b472:9320:xxxx:4df5/64 scope global temporary dynamic 
       valid_lft 604444sec preferred_lft 85834sec
    inet6 2600:1700:xxxx:83d:fb6b:19ca:xxxx:5e6/64 scope global dynamic mngtmpaddr noprefixroute 
<snip>

In this case, my IPv4 address, given by my router, is 192.168.0.11.

To find your public IP address:

curl https://ipinfo.io/ip

You should get a reply like:

1xx.140.129.95
