37) DHCP ________ are configurable parameters that determine which subnets the DHCP server will serve.

IP stands for ‘Internet Protocol’ and is made of numbers and periods. It is the

135.46.52.2. In binary this is 10000111.00101110.00110100.00000010. Again, we are looking at one of the Interfaces, so we take the 22 MSB’s, which

When setting up a network that will consist of many host computers, one of the first things that an administrator must do is to determine what class of networks that they must administer to a given business. This is the point where every administrator must know how to implement classful and classless IP addressing. A classful network is a network addressing architecture used in the internet from 1981 until the introduction of Classless Inter-Domain Routing (CIDR) in 1993. Classful IP addressing divides the addtess space on the internet into five address classes. Each class is coded in the first four bits of the address. Today

If we take the 172.16.0.0 range, that is /12. So that means that the network mask is 255.240.0.0. If we take 256-240 = 16 we get the block size which is 16. So that means that the range is from 172.16.0.0 to 172.31.255.255 because 172.32.0.0 is the next block and would be a public IP.

It is expressed as a dotted decimal number format to make it easier for human beings and the computer to remember.

6. A starting address of 192.0.0.0 and ending address of 223.255.255.255 is a member of which network class? Class C

Primary function of IP protocol = identify individual hosts and groups of hosts using the address

In CIDR notation, the IP address and subnet mask 191.9.205.22 255.255.192.0 are written as. B

If you used the number of bytes instead you would get a whole different amount of possible networks which isn’t right.

The TCP/IP protocols are the heart and soul of the Internet, and they describe the fundamental rules that govern all communications in the network. The original address system of the Internet is Internet Protocol version 4 (IPv4). The Internet Engineering Task Force (IETF) developed IPv6 to deal with the long-anticipated problem of IPv4 address exhaustion. However, IPv6 is not foreseen to supplant IPv4 instantaneously.

The second is Class B was designed for medium and large networks; the two main bits in Class B are always 10 which makes up the address. The next 14 bits are used to gather Class B I.Ds and instead they are set a length of 16-bit. The last 16 bits are used for the Host I.D. This allows for 16,384 networks and also 65,534 hosts to the network. Finally Class C which was designed for small networks. The three mains bits in Class C addresses are 110; the next 21 bits are used to gather Class C network I.Ds and Class C has a length of 24. Meaning the last 8 bits are for the Host I.Ds which means that Class C has 2,097,152 networks and 254 hosts.

Many organizations and companies ignore the importance of planning and administering a structured model approach to network layer addressing. Many problems result from such disorganization: there are duplicate network addresses; illegal addresses that routers cannot route to the Internet, running out of addresses for existing or future use; or have larger than required

What is IPv4? IPv4 is a 32-bit address used for communication between nodes using the TCP/IP protocol. The IPv4 address is broken into 4 octets each 8 bits long in binary and are broken into 5 different classes. Class A addresses start out where the first octet of the IP address ranged from 1-127 where 10 is reserved from private IP addresses. Class B addresses start out with 128 - 191 and has the 172.16.x.x to 172.31.x.x reserved from private IP addresses. Next is class C addresses that range from 192 - 223 in the first octet where 192.168.x.x is reserved from private IP addresses. Class D addresses range from 224 -239 in the first octet and are reserved from multicasting network traffic. Finally we have class E that range from 240 - 255 in the first octet and is reserved for experimental purposes ("IPv4," 2016).
