which bits are ignored. A wild card mask of 255.255.255.255
indicates that no bit is important. A wildcard of 0.0.0.0
indicates that all the bits are important. For example, if the
source IP address 149.36.184.198 and the wildcard mask

to which packets are addressed to the ACE.
Wildcard
Mask
Defines
the
destination
IP
address
wildcard mask.
