Configuring the domain name system (DNS)
The domain name system (DNS) lets you type a domain name in the address bar to connect to the
instrument. The DNS removes the requirement to memorize the IP address; instead you only need to
know the domain name.
Example:
Series2651A.yourcompany.com
NOTE
• If a DNS server is not part of the LAN infrastructure, this setting is not used.
• Contact your IT department to learn more about DNS.
To enable or disable DNS host name verification:
1. From the front panel, press the MENU key, and then select LAN > CONFIG > DNS > VERIFY.
2. Turn the navigation wheel
to select either ENABLE or DISABLE. When enabled, the
instrument performs a DNS lookup to verify the DNS host name matches the value specified in
the command lan.config.dns.hostname (on page 7-107).
3. Press
the ENTER key
.
4. Press the EXIT (LOCAL) key twice to return to the LAN CONFIG menu.
5. Select APPLY_SETTINGS > YES, then press the ENTER key.
To enable or disable DNS registration:
1. From the front panel, press the MENU key then select LAN > CONFIG > DNS > DYNAMIC.
2. Turn the navigation wheel
to select either ENABLE or DISABLE. DNS registration works with
the DHCP to register the host name specified in the lan.config.dns.hostname (on page 7-
107) attribute
with the DNS server.
3. Press the ENTER key.
4. Press the EXIT (LOCAL) key twice to return to the LAN CONFIG menu.
5. Select APPLY_SETTINGS > YES, then press the ENTER key.
