On October 13, 2026, at 00:00 UTC, Fastly will publish additional public IP address ranges to our Public IP List API endpoint. 

To prepare for future use, we recommend updating your IP prefix lists as soon as possible.

The following IP block(s) will be added to our range list:

• IPv4: 90.98.0.0/17 , 90.98.128.0/18

• IPv6: 2a04:4e42::/31 (expanded from 2a04:4e42::/32 ), 2a04:4e44::/32

The deployment of these new prefixes for active use is scheduled for January 11, 2027, at 00:00 UTC, and all currently published IP prefixes will remain unchanged.
