Issue

Description of problem: Hosts in IPv6-only networks cannot subscribe to RHSM using an IPv6 proxy address. The dual-stack proxy is necessary as RHSM currently still don't support IPv6. Version-Release number of selected component (if applicable): subscription-manager 1.29.33.1-1.el9_2 How reproducible: 100% Steps to Reproduce: 1. Provision host with IPv6 connectivity 2. Run `subscription-manager version --proxy="http://[<IPv6-of-your-proxy>]:3128 Actual results: The following blocks show you some examples of the the commands I tried. IP addresses were replaced with RFC 3849 prefix. ~~~ subscription-manager version --proxy="http://[2001:DB8::DEAD:BEEF:2]:3128" Traceback (most recent call last): File "/usr/sbin/subscription-manager", line 33, in <module> sys.exit(load_entry_point('subscription-manager==1.29.33.1', 'console_scripts', 'subscription-manager')()) File "/usr/lib64/python3.9/site-packages/subscription_manager/scripts/subscription_manager.py", line 73, in main return managercli.ManagerCLI().main() File "/usr/lib64/python3.9/site-packages/subscription_manager/managercli.py", line 87, in main ret = CLI.main(self) File "/usr/lib64/python3.9/site-packages/subscription_manager/cli.py", line 190, in main return cmd.main() File "/usr/lib64/python3.9/site-packages/subscription_manager/cli_command/cli.py", line 331, in main self.proxy_port = int(parts[1]) ValueError: invalid literal for int() with base 10: 'DB8' ~~~ The same 'ValueError' occurs when specifying the IPv6 address without the brackets '[]'.
