1.What are the mining URLs for Poolin?
URLs for all the coins can be viewed on the website.
Take BTC as an example:
For any other coins, please simply replace the btc part with other coins, such as eth:stratum+tcp://eth.ss.poolin.me:443
2.How to mine directly with IP address?
Please open CMD in your windows system, and enter ping eth.ss.poolin.me (just take eth as an example), press Enter
Then it will show you an IP address, you can then connect to Poolin with this IP address. (need to add port behind it, of course)
According to the screenshot above, my IP address is 126.96.36.199，this means I can connect to Poolin with stratum+tcp://188.8.131.52:443 or 184.108.40.206:443
