Network information

All requests originate from the IP ranges listed below. These ranges belong exclusively to Productsup — no other organization sends traffic from them — so there is no need to configure a proxy in the platform.

For more information about the Productsup network, see AS200249 on PeeringDB.

The /22 and /29 suffixes are CIDR notation — a compact way of writing a whole range of IP addresses in one line. Instead of listing every individual address, the suffix tells your firewall how large the range is. For example, 185.252.140.0/22 means "this address and the 1,023 addresses that follow it."

Most modern firewalls, load balancers, and server tools accept this CIDR format directly — paste the range as written and you are done.

Some older or simpler IPv4 tools split the range into two separate fields: a starting IP address and a netmask (sometimes called a subnet mask). The netmask is just a different way of describing the same range size. If your tool asks for both, use the values below.
