Normally, if we want to find the public IP Address we use, we go to google and search “,what is my, ip address”. But if you use Linux, you can get ,your, public IP Address from the command line using ,curl, command. The ,curl, command with ifconfig.me argument will show ,your, public IP Address.

8/1/2016, · On some of ,my, machines (mostly running Ubuntu 14.04) with libcurl 7.35.0 (tested up to libcurl 7.44.0), I am experiencing the following problem. When getting a DNS response that includes both an IPv4 and ,IPv6, response (like example.com), ,curl, chooses to attempt a ,IPv6, connection.

This is an issue with ,curl,, which has been fixed by the ,curl, people, but many OS distributions package old versions. Basically if ,curl, can find an ,ipv6, address for the domain in ,your, URL, then it'll try to fetch it, and if that fails, ,curl, fails, without falling back on trying the IPv4 address.

How do I force IPv4 or ,IPv6, lookup? As of 2018-07-25 it's no longer possible to force protocol using the v4 and v6 subdomains. IPv4 or ,IPv6, still can be forced by passing the appropiate flag to ,your, client, e.g ,curl, -4 or ,curl, -6. Is automated use of this service permitted? Yes, as long as the rate limit is respected.

Curl, now implements logic from the Happy Eyeballs algorithm, to smooth the transition to ,IPv6,, though that didn't make it to release 14.04. It was adopted in ,curl, 7.34.0 ( release history ), so it wasn't in Ubuntu at the time of the question (it is in 15.04).

curl, will connect to a server with ,IPv6, when a host lookup returns an ,IPv6, address and fall back to IPv4 if the connection fails. The --ipv4 and --,ipv6, options can specify which …
