| LABEL | DESCRIPTION |
|
|
|
| Name Server Record | A name server record contains a DNS server’s IP address. The ZyWALL can |
|
| query the DNS server to resolve domain names for features like VPN, DDNS |
|
| and the time server. |
|
| When the ZyWALL needs to resolve a domain name, it checks it against the |
|
| name server record entries in the order that they appear in this list. |
|
| A “*” indicates a name server record without a domain zone. The default record |
|
| is grayed out. The ZyWALL uses this default record if the domain name that |
|
| needs to be resolved does not match any of the other name server records. |
| # | This is the index number of the name server record. |
|
|
|
| Domain Zone | A domain zone is a fully qualified domain name without the host. For example, |
|
| zyxel.com.tw is the domain zone for the www.zyxel.com.tw fully qualified |
|
| domain name. |
| From | This field displays whether the IP address of a DNS server is from a WAN |
|
| interface (and which it is) or specified by the user. |
| DNS Server | This is the IP address of a DNS server. |
