What if packet size cannot be represented as a value divisible by 8?
Suppose a packet contains 23 bytes of data, and the MTU of the network is 1024 bytes. We have to make sure the data is divisible by 8. But in this case, that is not possible since if the data is represented as 24 bytes,there will be an extra byte (where do we get it [...]

Obfuscation of destination IP address
A self proclaimed security architect told me that there were hacking attacks where the hacker “obfuscated” the destination IP address to confuse the router into forwarding the packet out all of its interfaces and subsiquently the packet would live forever. In my limited knowledge I was a bit sceptical. Since he would not explain exactly [...]
