# Trivia Question 4
> Use the file. Get the flag. But, you know what, I hate pipes.
The file contained program written in Ook programming language. Running it gives string:```starting from 0.0.0.0, print the following IPs. 7277067th IP Address7234562th IP Address7302657th IP Address91238th IP Address746508th IP Address7211531th IP Address7300098th IP Address7211788th IP Address723558th IP Address91248th IP Address7237378th IP Address723557th IP Address7234562th IP Address723567th IP Address749067th IP Address
Hint: Anything specific about all the IPs?```Decoding those IP addresses to octet form, we get:```['0.111.10.10', '0.110.100.1', '0.111.110.0', '0.1.100.101', '0.11.100.11', '0.110.10.10', '0.111.100.1', '0.110.11.11', '0.11.10.101', '0.1.100.111', '0.110.111.1', '0.11.10.100', '0.110.100.1', '0.11.10.110', '0.11.110.10']```We can notice they all contain only 0's and 1's, so we treated them as ASCII characters to get string `zi|esjyougotivz`. After deleting `|` character (see description of task), the string was the expected flag.
