When managing a list of "Allowed Networks" within Slate for opening access for SFTP or Direct SQL Access, IP subnets can be entered using CIDR notation in addition to individual IP addresses. CIDR notation is an abbreviated way of including a subnet mask with an IP address to authorize an entire network of IP addresses. The following list provides two of the most common CIDR subnets that you might use:
|/24||For an example subnet of 123.123.123.[0-255] (the subnet mask is 255.255.255.0), you would enter 126.96.36.199/24. This would authorize all IPs ranging from 188.8.131.52 to 184.108.40.206. Please note that the "123" is for demonstration purposes only.|
|/16||For an example subnet of 123.123.[0-255].[0-255] (the subnet mask is 255.255.0.0), you would enter 220.127.116.11/16. This would authorize all IPs ranging from 18.104.22.168 to 22.214.171.124. Please note that the "123" is for demonstration purposes only.|
For a full list of CIDR subnets, review the Classless Inter-Domain Routing article in Wikipedia. For security purposes, Slate does not permit authorizing a subnet more expansive than /16 (for example, /8 is not supported).
