Trusted IP Ranges



We have couple of IP addresses added into Trusted IP Ranges. I would like to know more information about the range that is added into that.

If Start and end address is same , I feel that it might be IP address of a single user but if there is range how will I know more about it


Please suggest.

If you want to allow logins from a single IP address, enter the same address in both fields. For example, to allow logins from only, enter as both the start and end addresses.

The start and end IP addresses in an IPv4 range must include no more than 33,554,432 addresses (225, a /7 CIDR block). For example, the following ranges are valid: to to to

However, ranges like to or to are too large.


Every organization will have an IP range (Check with your Operation team) Ex: If the Ip ranges is in between to then the IP can access the salesforce instance without activating the system.
