The BoxCaster uses the Domain Name Service (DNS) to locate services it needs to use on the internet (e.g. the BoxCast website). If your network provides a network-local DNS server, the BoxCaster will utilize it. If a network-local DNS server is not present or is misconfigured, the BoxCaster will utilize Google's public DNS.
We fall back to external DNS in case a local DNS service is not present, compromised, or misconfigured. If you have a strict IT policy regarding external communications, we recommend you allow the BoxCaster to communicate with Google Public DNS servers (22.214.171.124 and 126.96.36.199); however, if you have a properly configured local DNS server that is provided in the DHCP reply, this is not necessary.
