ip range confusion

I saw the message in the source but I am confused :

When we say an IP range between 150 to 200 and 12 to 50 and if we

take in consideration that an IP address is composed of 4 numbers

what do we assume or advocate:

does this mean an IP like this :

(160 is between 150 and 200 - 20 between 12 and 50)

(minimum value - maximum value)

160.20.x.x

or like this

20.160.x.x

or like this

160.x.x.20

or

20.x.x.160

or

x.x.160.20

or

x.x.20.160

or

x.20.160.x

or

x.160.20.x

Range is around 200 to 230 and 23 to 91

Finding a proxy that actually works, never mind being in the correct range , made this challenge way harder than it should have been.

It's referring to the first set of number in the IP.

66.XXX.XXX.XXX. and. 218.XXX.XXX.XXX would be allowed access based on the above.

You need the first two numbers of the IP to match - it's about the network bits in the IP for different IP address classes.

In class B, 128.0.0.0 – 181.255.0.0 - u have 16 network bits and 16 host bits, so for example: 172.168.XXX.XXX network has a lot of combination for hosts (172.168.0.0 - 172.168.255.255)

Oh yeah, and good luck finding a proxy :)

I have the proxy and it is in the range and it works perfectly

this is the proxy :

208.40.x.x

However , I still cannot access the page . 403 forbidden

After solving this challenge , I would like to know why the range should be in the first two numbers of the ip address

for example

why 217.40.x.x and not x.217.40.x or x.217.x.40 ??

82.132.237.76 ……….. Good job, Some of you didn't even have to use a proxy to etc etc

200 to 230 and 23 to 91 is only referring to the first part of the IP address as far as I know, so anything starting between those 2 sets of numbers should be fine.

If it doesn't log you out of HBH when you click the link then the proxy prob doesn't work, HBH's cookies are IP based, so when your IP changes out you go.

Also, if you're just sitting on that page with the 403 error, and adding a new proxy and then refreshing it, that page is visible globally man, …. even if you're not logged in.

So on the off chance, If your proxy works, it would log you out , and you would still be sitting looking at that 403 error message

Thank you for the reply but unfortunately , you did not answer my question.

Why the range should be in the first two numbers of the ip address?

I hope I get an answer to my question

The range is set at your choosing to allow or deny access, it could be based on the first set of numbers being between the two ranges the challenge asks for here, or you can set a range for each part of the ip to further restrict access, or you could even create a whitelist of static ips to restrict it solely to an exclusive list.

If you mean why do this, the reason should be pretty obvious, controling access.

wonderful and clear thank you :)

Aye I love that guy. When I grow up I want to be just like him. thumbs up

of course
