To improve infrastructure resilience and scalability, new IP address ranges are being added to the Yousign platform.
Are you affected?
This update concerns organizations applying strict network security policies, specifically: - Incoming Traffic (Webhooks): If servers only accept requests from known IP addresses. - Outgoing Traffic (Corporate Firewall): If the internal network restricts outbound connections to specific IPs rather than domains.
📅 Effective Date: April 30, 2026
âš Action Required:
Your technical team must update your security configuration (Firewall / Allowlist) to authorize the new IP addresses below before this date.
New IP addresses to ADD: - 57.130.41.144/28 (Range: 57.130.41.144 -> 57.130.41.159) - 51.38.96.112/28 (Range: 51.38.96.112 -> 51.38.96.127)
Current IP addresses to RETAIN (Do not remove): - 5.39.7.128/28 (Range: 5.39.7.128 -> 5.39.7.143) - 52.143.162.31 - 51.103.81.166
Impact of inaction:
If your configuration is not updated by April 30, communications with Yousign may be blocked (webhook failures or inability to connect to the API/App).
