I have to give all IP ranges for login into my salesforce org. How can i do so?

Hi shubham ,

You can follow the below steps to give ip ranges :

From Setup, enter Network Access in the Quick Find box, then select Network Access.
Click New.
Enter a valid IP address in the Start IP Address field and a higher IP address in the End IP Address field.The start and end addresses define the range of allowable IP addresses from which users can log in, including the start and end values. If you want to allow logins from a single IP address, enter the same address in both fields.

The start and end IP addresses must be in an IPv4 range and include no more than 33,554,432 addresses (225, a /7 CIDR block).
Optionally, enter a description for the range. For example, if you maintain multiple ranges, enter details about the part of your network that corresponds to this range.
Click Save.
