    5. EA possible network address is 130.131.0.0
    6. FA possible network address is 130.131.255.255
  2. 2Consider the following IPv4 address structure and answer the following questions. Check all that applyImage for question 2
    1. AThis network may have up to 255 hosts.
    2. BThis network may have up 65 533 hosts
    3. CThis network may have up to about 16 mio. hosts
    4. DAs a standard classful network, the standard subnet mask is 255.0.0.0
    5. EAs a standard classful network, the standard subnet mask is 255.255.0.0
    6. FAs a standard classful network, its individual subnet mask could be 255.255.192.0
  3. 3Write down the base address and the direct broadcast address for the classful IP
    Network with the network number 212.126.53 and default network mask.
    base address = [blank_start]212.126.53.0[blank_end]
    direct broadcast address = [blank_start]212.126.53.255[blank_end]
    1. A212.126.53.0
    2. B212.126.53.255
  4. 4Write down the range of valid IP addresses which can be assigned to hosts in the IP
    network with the network number 212.126.53 and default network mask.
    first host address = [blank_start]212.126.53.1[blank_end]
    last host address = [blank_start]212.126.53.254[blank_end]
    1. A212.126.53.1
    2. B212.126.53.254
  5. 5Given a class B network 190.136.0.0 with fixed length subnet mask 255.255.192.0
    Representation of Net-Prefix Length 190.136.0.0 /[blank_start]18[blank_end]
    How many subnets are feasible (according to RFC 950)? [blank_start]4[blank_end]
    What is the maximum number of hosts in each subnet? Chose e.g. the first applicable subnet: [blank_start]2^14 - 2[blank_end]
    What is its subnet number (dotted decimal)? [blank_start]255.255.192.0[blank_end]
    1. A18
    2. B4
    3. C2^14 - 2
    4. D255.255.192.0

    2. B198.168.1.1
    3. C191.168.1.255
    4. D191.258.11.13
    5. E172.16.1.1
  7. 7Which of the following (classful) subnet masks are feasible or not for the listed network addresses?
    1. A193.168.3.0
      255.255.255.0
    2. B193.168.3.0
      255.255.0.0
    3. C193.168.3.0
      255.255.255.192
    4. D193.168.3.0
      255.255.255.221
    5. E10.0.0.0
      255.255.0.255
  8. 8Which facts hold for loopback addresses? Check all that applies.
    1. ADoes not access the physical network
    2. B127.0.0.1 is a loopback address
    3. CIt is a broadcast address to all hosts in the network
    4. DIt is defined as the “Localhost”
    5. EIt is reserved for link-local addressing
  9. 9Which facts hold for private IPv4 addresses? Check all that applies.
    1. ADoes not access the physical network
    2. BCan be applied to isolated hosts not directly accessible from internet
    3. CThere are 5 IP address ranges defined for private IP addresses
