Hello,
I made a small project on my Pi. I configured server, autostart, ports on router etc. but I don't know how to get an IP address without visiting the IP checking webpage like whatismyip.com (using LXDE and sitting right in front of my monitor in the house) ...
I have to have access to my Pi from everywhere by the internet (or in other words: I have to know what is the Pi's IP address). After some time the IP address will be changed right ?
Am I supposed to do anything to make my Pi's IP address static (for web) or something ?
I'm sorry for any language mistakes if they appeared.
I'm still learning this language.

Re: Internet IP Address
Which IP address do you want? Your LAN address or your public IPv4 address?
LAN address is easy
hostname -I # capital EYE
ifconfig -a
ip show addr
Because you can't get your public address without going out to somewhere on the internet and asking it to return the remote address that just connected.
sudo apt-get install dnsutils
dig +short myip.opendns.com @resolver1.opendns.com
curl -s http://httpbin.org/ip
With my home router (Technicolor TG582n) I can scrape the public ip address from the router's home page
curl -s -g "http://192.168.1.254/landing.lp?rs=getINFOIP" | tail -1

Re: Internet IP Address
Thanks for reply. I think I can't read my Pi's IPv4 without being connected to the same network :/DougieLawson wrote:Which IP address do you want? Your LAN address or your public IPv4 address?

It'd be stupid sending the IP address to the page whose IP address is unknown.
I think I'll just change my internet provider to another with "static public IP" (i don't know how to name it correctly).
Re: Internet IP Address
The situation of an ISP not giving a fixed public IP address is exactly what "dynamic DNS" providers cater for. Some are free to use and even for those that charge it may be cheaper than the additional charge from an ISP for a fixed address.
Many routers incorporate the necessary client to communicate with a small selection of dynamic DNS services. Or you can run one on a machine on your LAN.
