Yes, you can get provider independent IP adresses, and then use one a 'Bring Your Own IP'-type service at your infrastructure provider. Most cloud providers support this: https://aws.amazon.com/vpc/faqs/#Bring_Your_Own_IP https://aws.amazon.com/vpc/faqs/#Bring_Your_Own_IP https://www.ovhcloud.com/en/network/byoip/ https://www.ovhcloud.com/en/network/byoip/ https://docs.oracle.com/en-us/iaas/Content/Network/Concepts/BYOIP.htm https://docs.oracle.com/en-us/iaas/Content/Network/Concepts/... https://www.alibabacloud.com/solutions/bring-your-own-ip-addresses https://www.alibabacloud.com/solutions/bring-your-own-ip-add... https://cloud.google.com/vpc/docs/bring-your-own-ip https://cloud.google.com/vpc/docs/bring-your-own-ip It's definitely not going to be as simple, fleible and cheap as getting a domain name though. Using hard coded IP addresses for this kind of use case is almost certainly going to be giving you unexpected issues in the long run. Is there any chance you can use a hostname instead of an IP address to provide to your customers?

Using a hostname will be an improvement, but not perfect. It's going to depend on the firewall implementation whether it resolves the hostname to IP address one time and remembers it forever, or periodically refreshes the mapping. I've been particularly burned recently where the firewalls were on the other side of the country and geolocation came into play. The client machines resolved a hostname to A.A.A.A, but the firewalls resolved it to B.B.B.B, thus it looked right at first glance but still blocked the traffic.

We are using a domain name, but customer firewalls use fixed ip addresses.
