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 of the proxy connection. It is presented as a DNS name, because behind this address there are many IPv4 addresses (load balancers), and the IPv4 addresses may change.

8080 - Connection port. Ports do not affect IP address changes; they change only to select the protocol type

plan-limited-country-any-sid-nd1fmhz1mfxy - The login has such a long length that it can include the choice of country, region, and other parameters specified in the order settings. The login also contains sid-sy06witplz6x, it is responsible for the IP; changing a character will result in a change of the IP address. 7g6d8jd1t7in - Password for connection

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