IP address of 1.50.100.200
subnet of class 255.0.0.0 (class one)- what is the Network ID that is created and why? -
1.0.0.0
255 returns the top addr of 1 and 0 returns no information above it. - What octet numbers is Class C?
- 192-223
- How does classless Inter Domain Routing work. (CIDR)
- instead of using the four octets, it coveys decimal numbers to binary and use part of that.
- Class A licence
- (1-126) First Octet 1.0.0.0
- What is the purpose of a router?
- check
- In a class A, is 1.0.0.0 a valid IP address? In a class C, is 1.1.1.0 a valid address? why?
- you can not have zeros as the host ID.
- Why not get multiple class C liceneses for building?
- entry in routing table becomes large
- host ID must be unique in the local network.
- true dat
- What is CIDR?
- Classless inter domain rounting
- In a class C 192.230.123.32 what is the network ID and what is the host ID?
-
192.230.123 is network ID
32 is the host id. - What is the default subnet mask for a class A?
- 255.0.0.0
- What are the two ways to configure IP Addressing?
- Dynamically and Staticly
- Class B: how many octets available for manipulation?
- Two. Two are assigned.
- What is the default subnet mask for a class C Ip addr?
- 255.255.255.0
- What octet numbers is Class E?
- 240-255
-
1.50.100.200 ip address
255.255.0.0 subnet mask
What is the network ID? - 1.50.0.0
- Class C: how many octets available for manipulation?
- One. Three are assigned. 254 are the most hosts yuo can have
- What is the default subnet mask for a class B Ip addr?

- What octet numbers is Class B?
- 128-191. Note that 127 has been skipped. 127 is used for diagbnostic.
- what are the problems with classfull ip addressing
-
- class c licence 254 ip's
- class b licence 65,000 ip's
- class a 16 million ip's
wastefull. - Is 1.255.255.255 a valid IP address for use?
- no, 255.255.255 represents the broadcast address. In a class C 197.123.100.255 255 is still the broadcast code.
- What is a classfull IP addressing scheme?
- Using class A- E(experimental) to determine the first octet.
- What octet numbers is Class A?
- 1-126
- Class A: how many octets available for manipulation?
- Three. Only the first one is assigned.
- What octet numbers is Class D?
- 224-239
- IP address has two sections. What are they?
- They have a network and a host section.
- Class D: how many octets available for manipulation?
- none. They are all taken
