The DNS Health Checks module of our Route solution can monitor servers for a variety of DNS and performance-related factors. This type of monitoring requires each monitored server to allow access to our health check agents (i.e., servers). The IP addresses (IPv4 and IPv6) corresponding to our agents are listed below.
IP blocks (IPv4):
5.104.64.0/24 46.22.76.128/25 108.161.247.0/24 152.195.0.0/16 152.199.103.0/24 152.199.111.0/24 192.16.2.0/24 192.16.57.0/24 192.16.60.0/24 198.7.18.0/24 198.7.22.0/24
