Matching Pairs IPv4 addressing & ServicesOnline version In this activity, you will reinforce the concepts related to IPv4 addressing and services you have learned in class. by Juan Manuel Aranda Lopez King 1 PAT 2 netmask 3 subnetting 4 classless addressing 5 ACL 6 Public address 7 classful addressing 8 CIDR 9 Private address 10 VLSM 11 DHCP 12 NAT Refers to the concept that an IPv4 address has two parts: the prefix + host, as defined by the mask, with no consideration of the class (A, B, C). A mechanism for reducing the need for globally unique IP addresses. It allows an organization with addresses that are not globally unique to connect to the Internet, by translating those addresses into public addresses in the globally routable address space. A technique that optimizes the IP address space by using more than one mask in a single classful network. A list configured on a router to control packet flow through the router, such as to prevent packets with a certain IP address from leaving a particular interface on the router. A protocol used by hosts to dynamically discover and lease an IP address, and learn the correct subnet mask, default gateway, and DNS server IP addresses. Also known as NAT overload that allows supporting many clients with only a few public IP addresses. Allows creating multiple logical networks from a single address block. Refers to the concept that an IPv4 address has three parts: network + subnet + host, as defined by the mask and Class A, B, and C rules. Also called Prefix mask, that describes an IPv4 subnet mask when represented as a slash (/) followed by a decimal number (number of binary 1s in the mask). 198.8.3.32/24 192.168.0.1/24 Also known as Supernetting, an RFC-standard tool for global IP address range assignment, that helps to reduce the size of the IP routing tables and to deal with the rapid growth of the Internet.
