CSA – Networking Activity

On Monday’s Lecture, we were given this little activity to do! it was fun going back and remembering some of the old binary work I did, it was also good learning new ways to turn binary into decimals with a quick equation.

A) Change the following IPv4 addresses from binary notation to dotted-decimal nation.

1. 10000001   00001011    00001011      11101111  = 129.11.11.239
2. 11000001   10000011    00011011      11111111  = 193.131.26.255
3. 11100111   11011011    10001011      01101111  = 235.219.139.11
4. 11111001   10011011    11111011      00001111  = 249.155.251.15

B) Change the following IPv4 addresses from dotted-decimal notation to binary notation.

1. 111.56.45.78  = 01101111 00111000 00101101 01001110
2. 221.34.82  =  11011101 00100010 01010010
3. 241.8.56.12  = 11110001 00001000 00111000 00001100
4. 75.45.34.78  = 01001011 00101101 00100010 01001110

C) Find the error, if any, in the following IPv4 addresses:

1. 111.56.045.78  the 045 – it should be 45.
2. 221.34.7.8.20 this has to many numbers.
3. 75.45.301.14  301 because you can’t go higher then 255
4. 11100010.23.14.67 You can’t have a binary in a deciaml
