+  Get information about the IP ranges used when health-checking load balancers.
+---
+
+# google_compute_lb_ip_ranges
+
+Use this data source to access IP ranges in your firewall rules.
+
+https://cloud.google.com/compute/docs/load-balancing/health-checks#health_check_source_ips_and_firewall_rules
+
+## Example Usage
+
+```tf
+data "google_compute_lb_ip_ranges" "ranges" {}
+
+resource "google_compute_firewall" "lb" {
+  name    = "lb-firewall"
+  network = "${google_compute_network.main.name}"
+
+  allow {
+    protocol = "tcp"
+    ports    = ["80"]
+  }
+
+  source_ranges = ["${data.google_compute_lb_ip_ranges.ranges.network}"]
+  target_tags = [
+    "InstanceBehindLoadBalancer"
+  ]
+}
+```
+
+## Argument Reference
+
+There are no arguments available for this data source.
+
+## Attributes Reference
+
+In addition to the arguments listed above, the following attributes are exported:
+
+* `network` - The IP ranges used for health checks when **Network load balancing** is used
+
+* `http_ssl_tcp_internal` - The IP ranges used for health checks when **HTTP(S), SSL proxy, TCP proxy, and Internal load balancing** is used
