Primary DNS Server
Secondary DNS Server
The DNS is a system that pairs domain names with IP addresses. Host names and IP
addresses must be registered on the DNS server that handles the domain names in
order to access other instruments on the network by host name and domain name.
Also, on the MW100, the domain name is also used as a domain suffix.
On the MW100, you can specify two DNS servers. You must enter IP addresses. Consult
your network administrator for details.
Domain Name
Up to sixty-three alphanumeric characters can be entered.
The address is expressed using numbers. It is difficult to identify instruments on the
network with only a group of numbers. Therefore, you can assign domain and host
names to make it easier to distinguish different units.
When using a browser to connect to the MW100, you can specify the MW100 main unit
by specifying a domain and host name.
By specifying a unique host and domain name, you can access the MW100 without the
IP address. To make this possible, the host name of the MW100 must be registered on
the DNS server handling the domain names. Consult your network administrator for
details.
The MW100 supports dynamic DNS servers (DNS) in which host names are
automatically registered on the DNS server. To enable this function, select Register host
name on server. However, the DNS server must also support dynamic DNS. Consult your
network administrator for details.
Primary Domain Suffix
Secondary Domain Suffix
Up to sixty-three alphanumeric characters can be entered for the domain suffix.
The domain suffix is also referred to as a DNS suffix. When specifying the mail server
and other nodes only by host name, it is the domain name that is automatically
added. For example, if you set the domain name to mw100.com, the primary suffix to
DAQMASTER1.com, the secondary domain suffix to DAQMASTER2.com, and the mail
server to Mail, the MW100 queries the DNS server in the order:
1. mail
2. mail.mw100.com
3. mail.DAQMASTER1.com
4. mail.DAQMASTER2.com
and sends an e-mail message to the IP address obtained first, as the mail server.
