Update - Static proxy is a feature that ensures that webhooks egress Twilio from well-known IP addresses. Currently, customers who purchase Enterprise Plan, the Security & Legal Component of Enterprise Plan, or Static Proxy directly get access to Twilio through 4 static IP addresses. This allows customers to whitelist only those IPs in their firewalls and make the customer less exposed to attacks.



To meet an increase in demand and to better serve our customers, we are adding additional IP addresses to the Static IP range.



Between 10am-12pm PDT on Wednesday 4/17, Twilio will modify our system in a way that makes all webhooks originate from this new IP range. We will shut off the old range during this time. This means customers that have not properly whitelisted this new range will see 100% failure on webhook requests during this period.



Today Static Proxy webhooks originate from these IPs:



174.129.222.33

174.129.222.200

184.73.170.150

23.21.226.67




When we activate the new IP addresses, webhooks may egress from the following IP CIDR range (in addition to the above four addresses):



3.80.20.0/25 (equivalent to IPs 3.80.20.0 - 3.80.20.127)



After 12pm PDT on 4/17, we will switch off the new range and turn the old range back on.



Then, on 4/29 we will active the new IP range permanently, in addition to the original 4 addresses.



Please ensure you whitelist this new IP range before 4/17, to ensure your application continues to function as expected. If you have any questions, please contact your account representative or Twilio Support.
