IP Addressing and the Routing Process Flashcards
What is the range for Class A IP addresses?
Class A is 1 - 126
What is the range for Class B Ip addresses?
Class B is 128 - 191
What is the range for Class C IP addresses?
Class C is 192 - 223
True or False - Any address with a first octect of 227 is reserved for loopback interfaces
False - 127 is reserved for loopback interfaces
What is the default mask for a Class A address?
255.0.0.0
What is the default mask for a Class B address?
255.255.0.0
What is the default mask for a Class C address?
255.255.255.0
What is the range in each class for private addresses?
Class A: 10.0.0.0 - 10.255.255.255
Class B: 172.16.0.0 - 172.31.255.255
Class C: 192.168.0.0 - 192.168.255.255
True or False - Private addresses are referred to as “RFC 1918 Private Addresses”
True
A host at 192.168.1.100 wants to send packets to a host at 10.1.1.5, the sending host knows that 10.1.1.5 is not on the same subnet, what does the sending host do with the packets?
The sending host will send the packets to its default gateway
When a router receives a packet, there are three possibilities regarding its destination…what are they?
- Destined for a directly connected network
- Destined for a non-directly connected network that the router HAS and entry for in its routing table
- Destined for a non-directly connected network that the router does NOT have an entry for
What command would you use to show the ip routes?
Show ip route
What is a prefix notation?
Its a number that represents the number of 1’s a the beginning of the network mask when its expressed in binary. Example /8 would be 255.0.0.0 or 11111111.00000000.00000000.00000000
What command would you use to configure a static route?
ip route 0.0.0.0 0.0.0.0 192.168.0.1 (example)
