Health Check Workflow

1. When BloxOne When Infoblox Endpoint starts the proxy, it performs a health check for the cloud reachability. After that, BloxOne Infoblox Endpoint performs the health check periodically. 
2. For health checks, BloxOne  Infoblox Endpoint usually uses domains  ntp.ubuntu.com and pool.ntp.org.
3. A health check makes two subtests by using a domain: the tcp subtest and  udp subtest. They run simultaneously.
4. .Every subtest makes two queries. If both queries fail, BloxOne  Infoblox Endpoint  considers the system unhealthy. If either query is successful, BloxOne  Infoblox Endpoint  does not send another.
5. The interval between health checks for the proxy is one hour. However, if two client queries fail successively, BloxOne  Infoblox Endpoint does not wait for the interval to elapse and, instead, triggers the health check immediately.
6. If the health check fails, BloxOne  Infoblox Endpoint stops serving the DNS queries, goes to an unprotected state, and sets the status message to “You are not being protected by Infoblox BloxOne Endpoint Infoblox Endpoint because the Infoblox BloxOne DNS Infoblox DNS Server cannot be reached.”
7. If BloxOne If Infoblox Endpoint detects that a full VPN tunnel has intercepted any DNS query, , it goes to an unprotected state and sets the status message to “You are not being protected by Infoblox BloxOne Endpoint Infoblox Endpoint because some software (probably, a VPN client) intercepts DNS requests on this computer”.

Maximum number of concurrent DNS queries

BloxOne Endpoint Infoblox Endpoint can process up to 1000 concurrent DNS queries. If this limit is exceeded, the client will receive a DNS response with the response code SERVFAIL.

Maximum number of TCP connections

BloxOne Endpoint Infoblox Endpoint can serve multiple DNS queries through a single TCP connection sequentially: that is, by handling one DNS query at a time. However, if a client sends multiple queries simultaneously, BloxOne  Infoblox Endpoint can establish more than one connection. The maximum number of TCP connections is tied to the maximum allowed number of concurrent DNS queries: 1000.
