How to use Residential proxies

Let's consider what the proxy connection strings from the field in "Proxy list"

resident.proxyshard.com - This is the IP address for connecting to the proxy. It is presented as a DNS name because many IPv4 addresses (load balancers) sit behind this address and the IPv4 addresses can change.

8080 - The connection port. Ports do not affect changing the IP address; they change only to select the protocol type

plan-limited-country-any-sid-nd1fmhz1mfxy - The login, which is this long because it contains the choice of country, region, and other parameters specified in the order settings. Also the login contains sid-sy06witplz6x, it is responsible for the IP; changing a character will cause the IP address to change. 7g6d8jd1t7in - The password for connection

When creating a proxy list, they are not saved in the order, and when new proxies are created, the old proxies do not stop working. So at any time you can create as many proxies as you want without losing connection to the old ones.
