We don't really, hence things like

Yes, external lib is an option.
I expected that we already have something in the image.

Re: [Pharo-dev] Getting IP address of machine from Pharo

Ok, this one you can get it (for each network interface) via 

$ ifconfig

In the command line. So I guess it should be possible to ask the OS via a FFI 
call what is the address.

I don’t know what is done in Pharo about that.

Apparently, on Linux using C, it is possible to get the IP address of an 
interface via a call to getifaddrs [1].

I don’t know what is the method to do that on Mac OS.

I need address in my local network.

This is probably what you are looking for (one of the code snippets does 
exactly what you want).
http://forum.world.st/Figuring-out-external-IP-addresses-of-network-interfaces-td4937291.html
As for services/websites you can query to get the public ip address, here's a 
short list (you'll have to modify the example above to parse the response 
correctly):
http://checkip.dyndns.com
https://www.whatismypublicip.com/
http://freegeoip.net
https://who.is/
http://www.ipchicken.com/
http://www.whatsmyip.org/
https://api.ipify.org/
https://whatismyipaddress.com/

IMHO, the simplest is api.ipify.org.  However, note that some of those service 
also answer geolocation info!

 Hello.
Do we have a way to retrieve IP address from Pharo?I tried to use following 
code:


NetNameResolver addressForName: NetNameResolver localHostName 


But it either not works (dialog with retry give-up options) or returns 
localhost 127.0.0.1.

Re: [Pharo-dev] Getting IP address of machine from Pharo

[Julien]

What do you mean by your IP address, on your local network or the one seen by 
external servers when you connect to them?

If I remember well, the IP address seen by computers outside your local network 
is not the IP address of your actual computer but the one of the router 
connecting your local network to the outside web.

I am not sure you can get the outside IP address without asking it to a 
computer outside your local network but I might be wrong.
