DNS to local network

The SINAUT MD741-1 provides a domain name server (DNS) to the local network.
If you enter the IP address of the SINAUT MD741-1 in your local application as the
domain name server (DNS), then the SINAUT MD741-1 answers the DNS queries
from its cache. If it does not know the corresponding IP address for a domain
address, then the SINAUT MD741-1 forwards the query to an external domain name
server (DNS).

The time period for which the SINAUT MD741-1 holds a domain address in the
cache depends on the host being addressed. In addition to the IP address, a DNS
query to an external domain name server also supplies the life span of this
information.
