IP and Domains

If your network restricts outbound external access, you need to add Nocoly's IPs and domains to your allowlist to ensure normal usage.

The allowlist has two directions—outbound and inbound—with different purposes and addresses. Please configure them separately.

Outbound: Nocoly Accessing Your System

When Nocoly initiates outbound requests, the source IP is fixed to one of the 5 addresses below (Tencent Cloud Hong Kong), randomly selected for each request. If your system (internal APIs, code repositories, messaging services, etc.) restricts source IPs, you need to allow all 5 of these:

43.154.235.158
43.154.111.184
43.154.63.239
43.154.158.53
43.154.202.180

This applies to the following three types of outbound scenarios, which share the same set of egress IPs:

Scenario	Description
Webhook	Outbound pushes from workflow and worksheet events
Sending API requests	External API calls made by workflow nodes
Code block	External access from custom code within a workflow

Inbound: You Accessing Nocoly

If your outbound policy filters by destination address, you need to allow the following domains:

Domain	Purpose	Resolution for Mainland China, Hong Kong, Macao, and Taiwan
www.nocoly.com, nocoly.com	Main platform site	101.32.18.60
status.nocoly.com	Service status page	101.32.18.60
wps.nocoly.com	Online Office document preview and editing	43.154.93.3

Important: For other regions, allow by domain, not by IP. www.nocoly.com uses multi-line resolution: in Mainland China, Hong Kong, Macao, and Taiwan, it resolves directly to the IP shown in the table above; in other regions, it is accelerated via CDN and returns the IP of the nearest CDN node, which changes depending on the access location and time (results queried from different regions may be completely different). Therefore, in network environments outside Mainland China, Hong Kong, Macao, and Taiwan, only the domain can be added to the allowlist—configuring by IP will become invalid once the node changes.
