| Question | Answer |
|---|---|
| A network address that all other hosts on a network must read | broadcast address |
| Translates IP addresses to a MAC Address | ARP |
| Decimal equivalent of binary 11111111 | 255 |
| This service lets networks use multiple private IP addresses internally and maps to one public address externally | NAT |
| Each time a data frame crosses another router it is considered this | A hop |
| Subnet masking where one network address can be broken into multiple subnets of equal size | constant-length subnet masking |
| Subnet masking where one network address can be broken into multiple subnets of variable sizes | variable-length subnet masking |
| default subnet mask of Class B network | 255.255.0.0 |
| Range of the first octet for a Class A address | 1 - 127 |
| default subnet mask of Class C network | 255.255.255.0 |
| Range of the first octet for a Class B network | 128 - 191 |
| Range of the first octet for a Class C network | 192 - 223 |
| default subnet mask of a Class A network | 255.0.0.0 |
| Number of usable hosts in a default Class C network | 254 |
| Binary representation of 96 | 01100000 |
| Physical numeric address | MAC address |
| Default Class of IP addresses that include the most host addresses | Class A |
| Default Class of Ip addresses that include the most network addresses | Class C |
| Loopback address | 127.0.0.1 |
| Version of IP most commonly used today. Version we are learning. | IPv4 |
| Private IP address range for Class A network | 10.0.0.0 - 10.255.255.255 |
| bit pattern that masks off the network portion of an IP address with all 1s | subnet mask |
| Private IP address range for a Class C network | 192.168.0.0 - 192.168.255.255 |
| Private Ip address range for a Class B network | 172.16.0.0 - 172.31.255.255 |
| Decimal for 11110000 | 224 |
| Network prefix for subnet mask 255.255.255.192 | /26 |
| 01001000 in decimal | 72 |
| 86 in binary | 01010110 |
| In the subnet mask identifies the host portion | zero |
| Is this a usable address on the Internet? 10.5.6.7? | No, it is a Private address and is not routable. |
| Is this a usable address on the Internet? 200.256.10.8? | No, we can not use any number in an octet higher than 255. |
| Is this a usable address on the Internet? 15.14.14.14 | Yes |
| Is this a usable address on the Internet? 172.23.10.10 | No, It is a Private address for Class B and is not routable on the Internet. |
| Is this a usable address on the Internet?200.5.5.5 | Yes |
| Is this a usable address on the Internet? 225.16.16.16 | No, it belongs to a class D network which is used for multicast only. |
| Is this a usable address on the Internet? 127.16.16.5 | No, the entire 127 network is used for loopback purposes only. |
| Identify the network portion based on the following:195.16.10.5255.255.0.0 | 195.16.0.0 |
| ID the host portion based on the following:15.7.80.25255.255.255.0 | 0.0.0.25 |
| Default class that will give us the most networks | Class C |
| Default class that will give us the most hosts | Class A |
