How do I set the Domain Name Issued by the DHCP Server?

If you require your DHCP clients to be allocated a specific domain name, you can set this option via the router telnet interface.

Single WAN Vigor Routers

On single WAN routers (for example Vigor2800) use the command:

sys domainname [Domain Name Suffix]

For example to set a domain suffix of myname.com.au use the following command:

“sys domainname myname.com.au”

To check the current domainname setting use the following command:

sys domainname ?

Dual WAN Vigor Routers

On dual WAN routers (for example Vigor2820) use the command:

sys domainname <wan1/wan2> <Domain Name Suffix (max. 40 characters)>

For example if you are using WAN1 wish to set a domain suffix of myname.com.au use the following command:

“sys domainname wan1 myname.com.au”

To check the current domain name setting use the following command:

sys domainname ?

Verify DHCP has issued domain name

In the computer windows command prompt type “ipconfig /renew “. This will verify that DHCP has issued the desired DNS Suffix.
