IP Addressing Flashcards
CompTIA A+ 220-1201 (V15) Flashcards
| Front | Back |
| Anycast | Delivered to the nearest interface |
| APIPA Range | 169.254.0.0-169.254.255.255 |
| Broadcast | Delivered to any interface or node in the same LAN. IPv4 only. |
| CIDR Notation | A method for allocating IP addresses and routing that uses a suffix (e.g. /24) to indicate the network prefix length instead of traditional classes |
| Default Gateway | The network node that acts as the primary forwarding point for traffic destined for networks outside the local subnet; typically a router |
| DHCPv6 | A protocol that assigns IPv6 addresses and configuration parameters to devices from a central server similar to DHCP in IPv4 |
| IP | Internet Protocol |
| IPv4 | Internet Protocol version 4; 32 Bits |
| IPv4 Class A Range | 1.0.0.0 to 126.0.0.0 |
| IPv4 Class B Range | 128.0.0.0 to 191.255.255.255 |
| IPv4 Class C Range | 192.0.0.0 to 223.255.255.255 |
| IPv4 Loop-back Address | 127.0.0.1 |
| IPv6 | Internet Protocol version 6; 128 Bits |
| IPv6 Global | IPv6 version of public addresses. Must be unique and are usable on the Internet. |
| IPv6 Link-Local | IPv6 version of APIPA. Automatically configured, and only usable on local segment. (fe80::/64) |
| IPv6 Site-Local | IPv6 version of Private Addressing. Only usable within a single organization or site. Not usable on Internet. (fc00::/7) |
| Maximum Transmission Unit (MTU) | The largest size of an IP packet that can be transmitted in a single network layer transaction without requiring fragmentation |
| Multicast | Delivered to a group of interfaces or nodes. |
| NAT | Network Address Translation. Translates IP Addresses between different networks. Typically between a public and private network |
| NAT vs PAT | A comparison where NAT translates whole IP addresses while PAT allows multiple devices to share a single IP address by differentiating sessions using port numbers |
| Private Class A Range | 10.0.0.0 to 10.255.255.255 |
| Private Class B Range | 172.16.0.0 to 172.31.255.255 |
| Private Class C Range | 192.168.0.0 to 192.168.255.255 |
| Private IP Address | Usable only on private networks. Can not be routed through the Internet |
| Public IP Address | Usable on both private and public networks. Can be routed through the Internet, as long as the IP Address is unique |
| Reserved IPv4 Addresses | Special IPv4 addresses such as 0.0.0.0 for the default route and 255.255.255.255 for broadcast that are reserved for specific network functions |
| Subnet Mask | A 32-bit number used in IPv4 to divide the address into network and host portions; common notation is 255.255.255.0 |
| Unicast | Delivered to one interface or node |
