For Schools: Which domains should I whitelist?

Whitelisting may be necessary if your school’s network has banned external service providers (like 99math). 

You can check this by going to our Health Check page here: www.99math.com/health-check.

If any of the categories are red, you might need to whitelist our domains. Instead of specific IP ranges, we recommend DNS-based whitelisting. 

Please whitelist the following domains to ensure 99math’s core functionality. If your filter supports wildcards, *.99math.com covers all of our own domains, including new game servers we add over time:

• *.99math.com
• 99math.com
• www.99math.com
• core.prod-eu.99math.com
• tbl.prod.99math.com
• *.tbl.prod.99math.com (live game servers, e.g. tbl0.tbl.prod.99math.com, tbl1.tbl.prod.99math.com)
• game.prod.99math.com (the 99 Pets game)
• community.99math.com
• demo.99math.com

If your teachers or students sign in with Google or Clever, also allow:

• accounts.google.com
• apis.google.com
• clever.com
