This command adds a rule to a Standard IPv4 ACL. The rule sets a filter
permit, deny
condition for packets emanating from the specified source. Use the no
(Standard IP ACL)
form to remove a rule.

◆
Address bit masks are similar to a subnet mask, containing four
◆
integers from 0 to 255, each separated by a period. The binary mask
uses 1 bits to indicate "match" and 0 bits to indicate "ignore." The
bitmask is bitwise ANDed with the specified source IP address, and then
compared with the address for each IP packet entering the port(s) to
which this ACL has been assigned.

This example configures one permit rule for the specific address 10.1.1.21
and another rule for the address range 168.92.16.x – 168.92.31.x using a
bitmask.
Console(config-std-acl)#permit host 10.1.1.21
Console(config-std-acl)#permit 168.92.16.0 255.255.240.0
Console(config-std-acl)#
