Description

I asked my friend for the IP addresss of their website and this is what they gave me. I’m sure they’re misunderstanding, but I should really decode this before deciding that. Remember to enter your answer in the “flag{…}” format! 1.9.100.51.110.116.105.102.105.51.100

Solution

Here we get the strange looking IP address 1.9.100.51.110.116.105.102.105.51.100.

After converting each of the values 100.51.110.116.105.102.105.51.100 from decimal we get the string d3ntifi3d.

Adding the 1 from the beginning of the original string we get the flag.

flag{1d3ntifi3d}
