Flashcards in Chapter 7 Deck (11):
IP address is ______
Internet Protocol address, an IP or IP address is an address of a computer or other network device on a network using TCP/IP. For example, the number "18.104.22.168" is an example of such an address.
Network address is _______
The network portion of an IP address. For a class A network, the network address is the first byte of the IP address. For a class B network, the network address is the first two bytes of the IP address. For a class C network, the network address is the first three bytes of the IP address. In each case, the remainder is the host address.
Class A addresses:
Class A addresses are assigned to networks with a very large number of hosts. The high-order bit in a class A address is always set to zero. The next seven bits (completing the first octet) complete the network ID. The remaining 24 bits (the last three octets) represent the host ID. This allows for 126 networks and 16,777,214 hosts per network.
Class B addresses:
Class B addresses are assigned to medium-sized to large-sized networks. The two high-order bits in a class B address are always set to binary 1 0. The next 14 bits (completing the first two octets) complete the network ID. The remaining 16 bits (last two octets) represent the host ID. This allows for 16,384 networks and 65,534 hosts per network.
Class C addresses:
Class C addresses are used for small networks. The three high-order bits in a class C address are always set to binary 1 1 0. The next 21 bits (completing the first three octets) complete the network ID. The remaining 8 bits (last octet) represent the host ID. This allows for 2,097,152 networks and 254 hosts per network.
when all host bits are turned off we have the _____
10.0.0.0 for class A
127.16.0.0 for class b
192.168.100.0 for class C
when all host bits are turned on we have the _____
10.255.255.255 for class A
127.16.255.255 for class B
192.168.255.255 class C
what is private IP address definition?
Private IP addresses are provided by network devices, such as routers, using network address translation (NAT).
What is APIPA?
APIPA. (Automatic Private IP Addressing) The Windows function that provides DHCP autoconfiguration addressing. APIPA assigns a class B IP address from 169.254.0.0 to 169.254.255.255 to the client when a DHCP server is either permanently or temporarily unavailable.
what is IPv4 ?
Internet Protocol version 4 (IPv4) is the fourth version in the development of the Internet Protocol (IP). It is one of the core protocols of standards-based internetworking methods in the Internet
