These are the Access-list which are made using the source IP address only. These ACLs permit or deny the entire protocol suite. They don’t distinguish between the IP traffic such as TCP, UDP, HTTPS, etc. By using numbers 1-99 or 1300-1999, the router will understand it as a standard ACL and the specified address as the source IP address.
