I'm trying to use a proxy with my wallet that requires authentication. I couldn't find a whole lot on this, but I was able to get the wallet to launch and connect to the network with the option "-proxy=proxyusername:proxypassword@proxyaddress.com:23". However, I'm not sure if it's working or not. How can I check the address my wallet is using, to check if it is using the proxy? Is there a console command or other way I can view it? Thanks.
You don't need to do things like that. I suggest you to use Tor, VPN or public wifi for hiding your ip. You could google how to set up them. There is no need to configure the bitcoin wallets you are using. I got one tutorial for you!
