14.1 Speed Touch DNS Resolving
The AST710 features a DNS server for the locally attached PCs,
and as DNS relay for nonlocal DNS hostnames.
The same mechanism for resolving computer names to IP
addresses when browsing the Internet, applies to your local
network.
Instead of using the IP addresses for a local IP node e.g.
10.0.0.138 for the AST710 , you can give your nodes names and
let a local DNS server, e.g. the AST710 itself, do the resolving.
In the following example, a LAN is built around the AST710 .
In this scenario, it is assumed that the AST710 acts as DHCP
server, and as DNS server for the local network.
During startup, a first PC launches a DHCP request on the LAN.
One of the fields in the DHCP request contains the computer
name e.g. YourPC .
The AST710 reacts by intercepting this request and returns
a DHCP reply containing:
The IP address for his computer, e.g. 10.0.0.1
The local domain name, e.g. lan (default)
The IP address of the local DNS server, e.g. 10.0.0.138 being
the AST710 (default).
A second PC, named MyPC , is powered on and is configured via
a DHCP reply as below:
The IP address for his computer, e.g. 10.0.0.2
The local domain name, i.e. lan
The IP address of the local DNS server, i.e. 10.0.0.138.
In the example scenario, it is now possible to ping both PCs,
MyPC and YourPC , by referring to their computer names instead of
their IP addresses.
