IP Address Converter

Question

There is IP address: 66.102.13.19, and from this address as that received this address

http://1113984275

But how? And how I can make this

Answer 1

I think there's a simpler solution that also handles an arbitrary number of octets with no references to fixed offsets etc.

echo 66.102.13.19 |
    tr . '\n' |
    while read octet; do
        printf "%.08d" $(echo "obase=2;$octet" | bc)
    done |
    echo $((2#$(cat)))

output: 1113984275
