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.
