Procedure

1. Retrieve the IP address available in the regional Cloudflare trace page.

   Trace page format:

   https://<region>.lakehouse.cloud.ibm.com/cdn-cgi/trace
   

   For example:

   https://eu-de.lakehouse.cloud.ibm.com/cdn-cgi/trace
   

   Output:

   fl=374f35
   h=eu-de.lakehouse.cloud.ibm.com
   ip=171.76.80.113
   ts=1712133673.168
   visit_scheme=https
   uag=Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/123.0.0.0 Safari/537.36
   colo=BLR
   sliver=010-tier3
   http=http/2
   loc=IN
   tls=TLSv1.3
   sni=plaintext
   warp=off
   gateway=off
   rbi=off
   kex=X25519
   

2. Add the IP address that is retrieved from the trace page to the allowed IP address list and click Save.

   The IP address that is displayed with Hint might not match with the one available in the trace page. Add the value from the trace page instead of the value with Hint.

   To add multiple IP addresses in a range, use a CIDR block. For example, if you want to include all IP addresses between 171.76.80.0 and 171.76.80.255, include the CIDR block 171.76.80.128/24.
