Network information
Productsup IP ranges for allowlisting on your firewall or remote servers.
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.
You must allowlist the entire range, not a single IP address. Productsup might use any address in these blocks, and the specific source IP for any given request is not stable.
Productsup IP ranges
- IPv4:
185.252.140.0/22 - IPv6:
2a13:7840::/29

CIDR and netmask notation
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.
| CIDR | Starting IP | Netmask |
|---|---|---|
185.252.140.0/22 | 185.252.140.0 | 255.255.252.0 |
IPv6 has no netmask equivalent — the protocol only uses CIDR notation (the /29 prefix length). Enter 2a13:7840::/29 directly wherever your tool accepts an IPv6 range.
