Load Balancer IP Addresses – Rezolve Ai Support Portal

Attraqt Fredhopper Services use multiple load balancers, and a DNS round-robin approach for them. Depending on the network infrastructure on the front-end it may be necessary to white list the IP addresses of the Attraqt Fredhopper services in the firewalls for inbound and outbound traffic.

For full hostnames to be used in queries check: API Reference.

Connecting directly to IP addresses

We advise to not directly connect to the IP addresses of the Attraqt Fredhopper Managed Service for the following reasons:
Attraqt uses a DNS service that distributes requests to the IP addresses of various load balancers.

In case of a failing load balancer, the DNS service ensures that all traffic is forwarded to one of the
working load balancers. You will lose this additional fail safeness when connecting directly to the IP addresses.
Therefore the Attraqt SLA for service availability does not apply for integration against IP addresses.
Attraqt aims to not change the IP addresses, but Attraqt can neither guarantee that they won't change nor that you will be informed beforehand about such changes.

TTL
Please respect the 'Time To Live' (TTL) of the DNS records of the Attraqt Fredhopper services domains. Not doing so can cause "connection refused" in your front-end when we do maintenance.
