Captcha on IPs

it wont let me post a new topic.

Anyone else now getting captcha request for https://www.cloudflare.com/ips-v4/ and https://www.cloudflare.com/ips-v6/ from there automated scripts?

script been running fine for years, but now seems they have put those endpoints behind a captcha which cant be automated… Seems like an oversight?

no problems here

curl -4s --max-time 20 --connect-timeout 20 https://www.cloudflare.com/ips-v4/
173.245.48.0/20
103.21.244.0/22
103.22.200.0/22
103.31.4.0/22
141.101.64.0/18
108.162.192.0/18
190.93.240.0/20
188.114.96.0/20
197.234.240.0/22
198.41.128.0/17
162.158.0.0/15
104.16.0.0/13
104.24.0.0/14
172.64.0.0/13
131.0.72.0/22

how are you pulling the IPs script wise?

Probably your IP address is having a bad reputation?

403

Failure to retrieve IPv4 and IPv6 text lists.
We have confirmed that a 403 error is returned on all servers hosted by VULTR when requesting with curl.
https://www.vultr.com/

The first it had already occurred around 2022-03-16 17:00 for UTC time.
This seems to be a massive problem.

Hi @MattHuisman and @solt,

Do either of you have a ticket open for this issue? If not, please email [email protected] from your account email address. When you get an autoresponse with a ticket number, please post that here so i can get this escalated to the right people.

im using VULTR as well (Sydney node)
Its IP hasnt changed in years though…

I can reproduce this error on a Vultr VM,

I’ve raised a ticket from a Business zone

also seems to be fixed for me

Thing to note: it appears doing a HEAD request will give you a 403 error:
curl -LI https://www.cloudflare.com/ips-v4/ -o /dev/null -w '%{http_code}\n' -s
403

curl -L https://www.cloudflare.com/ips-v4/ -o /dev/null -w '%{http_code}\n' -s
200
