Ventures runs on a web farm with multiple services running different parts of our software. This means that Ventures does not have a single outbound IP address, instead we have a pool of IP addresses. Ventures traffic can come from any IP address in the pool. The addresses within the pool do not change. Depending on how your network security is setup, this may cause issues with some Ventures services. If you are encountering errors communicating with Ventures, asking your IT team to add the following IP addresses to the your firewall's whitelist may solve your issue. The pool contains 43 addresses, they are listed below:

20.245.176.70, 20.228.95.95, 20.228.95.96, 20.228.95.227, 20.237.175.247, 20.66.45.207, 20.237.241.40, 20.237.241.29, 20.237.241.230, 20.237.242.20, 20.237.242.45, 20.237.241.218, 20.66.42.149, 20.66.44.155, 20.66.56.187, 20.237.171.11, 20.66.58.18, 20.66.58.57, 20.66.58.64, 20.245.177.80, 20.66.58.66, 20.66.45.209, 20.66.58.181, 20.66.59.64, 20.66.59.71, 20.66.46.96, 20.66.59.224, 20.66.60.135, 20.66.60.232, 20.66.61.53, 20.237.241.40, 20.237.241.29, 20.237.241.230, 20.237.242.20, 20.237.242.45, 20.237.241.218, 20.237.242.142, 20.245.177.92, 20.66.61.170, 20.66.61.223, 20.66.62.19, 20.237.171.198, 40.112.243.108
