IP Addresses

Some payment gateways and payment method receivers require incoming requests to only come from white-listed IP Addresses. There are 3 ways to specify a set of IP addresses. You can use CIDR notation, you can use subnet masks, or you can list all of the IP’s. You only need to use one of the three specification methods.

Using CIDR notation

If your gateway or receiver allows you to use CIDR notation, please specify the following:

50.31.145.128/28
167.88.149.176/28

Using subnet masks

If your gateway or receiver allows you to specify subnet masks, please specify the following:

IP Address: 50.31.145.128
Subnet Mask: 255.255.255.240

IP Address: 167.88.149.176
Subnet Mask: 255.255.255.240

IP Address

If your gateway or receiver doesn’t allow you to use CIDR notation and it doesn’t allow subnet masks, list the following IP address:

167.88.149.182
