Solution
Answer:
193.65.72.0/24
193.65.73.0/24
193.65.74.0/24
193.65.75.0/24
193.65.75.0/24
193.65.76.0/24
First step:
For summarising the routes the first step should notice that the range of networks .in this it is identified in the third octet since the first octet and second octet are same .
Second step:
72=0100 1000
73=0100 1001
74=0100 1010
75=0100 1011
76=0100 1100
Mask :1111 0000
Second step:
The second step is to find out the binary values of the network range . the binary range for the third octet are determined. From this the first 4 bits are all the same. The change in the range is essentially happening in the last 4 bits in the third octet .
Third step: Identifying and masking the common bits in a summary.
The next step is to identify those common bits. Tosummarize is to build a subnet mask that puts a 1 under all of the common bits in the range, and a 0 under everything else.
Fourth step:
The fourth step is to actually create the summary statement. A summary is an IP address and a mask
The IP is usually a network ID
For the mask, the first and second octet is the same in the range, first four bits in the third octet are always the same. Thus 8 bits in the first octet and 8 bits in the second octet and the first 4 in the third octet.
=>11111111. 11111111 .11110000. 00000000
This can be written as
=>255.255.240.0
=>192.65.72.0 255.255.240.0
