🌍See the World

What should we do?

We're very protective over our guy, even with his eight cylinders under the hood! he's dying for an exodus into the world, even if he lacks the intelligence to do so safely (i mean, it doesn't even have a sandbox!) anyway, if you give us an IP and it all checks out, we'll let him pop by and check it out for a bit, and let him see the world. what's the worst that could happen? (The flag is safe with us though, at /flag.txt.)

user@pc:~/Desktop$ nc challenge.nahamcon.com <port>
welcome to our browser! give me an IP and, if it checks out, we'll let him visit.
>>> localhost
what is this nonsense
>>> 127.0.0.1
hm maybe this is fine, gotta check it though before the browser can visit...this IP didn't even give me a 200! That's not good enough for our browser to visit.
>>> 192.168.1.1
