DNS

DNS

The following sections describe the configurations of dynamic DNS entries, domain name server, domain name suffix, and enabling dynamic domain name resolution.

In addition to distinguishing devices by IP addresses, TCP/IP provides the Domain Name System (DNS) to name hosts by using character strings. DNS uses a hierarchical naming method to specify a meaningful name for a device on the network. In addition, a DNS server is required on the network to bind IP addresses to domain names. The DNS server enables users to use simple domain names instead of complex IP addresses.

Dynamic DNS Entry Table

You can view the dynamic DNS entries.

Context

The deleted dynamic DNS entries cannot be restored; therefore, perform the deletion operation with caution.

Procedure

  1. Choose System Management > DNS > Dynamic DNS Entry Table in the navigation tree to open the Dynamic DNS Entry Table page, as shown in Figure 2-56.

    Figure 2-56  Dynamic DNS Entry Table

  2. View dynamic DNS entries. To delete all dynamic DNS entries, click Clear All. The system asks you whether to delete all dynamic DNS entries. The deleted dynamic DNS entries cannot be restored.
  3. Click OK.

DNS Settings

Dynamic domain name resolution requires a special DNS server. This server maps domain names to IP addresses and processes the resolution requests of clients.

Context

After receiving a resolution request, the DNS server checks whether the domain name belongs to its authorized sub-domain. If yes, the server translates the domain name into an IP address according to the database, and then sends the result to the client. If the server cannot resolve the domain name, it sends the resolution request to the upper-level DNS server. This process continues until the DNS server finds the corresponding IP address or detecting that the corresponding IP address does not exist. The DNS server then returns the result to the DNS client.

Procedure

  • Create a DNS server.
    1. Choose System Management > DNS > DNS Settings in the navigation tree to open the DNS Settings page.
    2. Click Create to open the Create a DNS Server page, as shown in Figure 2-57.

      Figure 2-57  Create a DNS Server

    3. Set parameters.
    4. Click OK.
  • Delete a DNS server.
    1. Choose System Management > DNS > DNS Settings in the navigation tree to open the DNS Settings page.
    2. Select a record that you want to delete and click Delete. The system asks you whether to delete the record.
    3. Click OK.

Domain Name Settings

The system provides the domain name suffix list. You can preset domain name suffixes.

Context

  • Users only need to enter partial content of a domain name, and then the system adds a suffix to the domain name for resolution.
  • For example, you have set the domain name suffix com in the suffix list. If a user wants to visit huawei.com, the user only needs to enter huawei. Then the system adds the suffix com to huawei.com.

Procedure

  • Create a domain name suffix.
    1. Choose System Management > DNS > Domain Name Settings in the navigation tree to open the Domain Name Settings page.
    2. Click Create to open the Create a Domain Name Suffix page, as shown in Figure 2-58.

      Figure 2-58  Create a Domain Name Suffix

      Table 2-22 describes the parameters on the Create a Domain Name Suffix page.

      Table 2-22  Create a Domain Name Suffix

      Parameter

      Description

      Domain name suffix

      Indicates the new domain name suffix, for example, com.

    3. Set parameters.
    4. Click OK.
  • Delete a domain name suffix.
    1. Choose System Management > DNS > Domain Name Settings in the navigation tree to open the Domain Name Settings page.
    2. Select a record that you want to delete and click Delete. The system asks you whether to delete the record.
    3. Click OK

Enable Dynamic Domain Name Resolution

To use the dynamic domain name resolution function, you must enable it first.

Context

Dynamic domain name resolution requires a special DNS server. This server maps domain names to IP addresses and processes the resolution requirement of clients.

Procedure

  1. Choose System Management > DNS > Enable Dynamic Domain Name Resolution in the navigation tree to open the Enable Dynamic Domain Name Resolution page, as shown in Figure 2-59.

    Figure 2-59  Enable Dynamic Domain Name Resolution

    Table 2-23 describes the parameters on the Enable Dynamic Domain Name Resolution page.

    Table 2-23  Enable Dynamic Domain Name Resolution

    Parameter

    Description

    Enable dynamic domain name resolution

    Indicates whether to enable the resolution function. You can set the DNS parameters before enabling the resolution function, but the DNS parameters take effect only after you enable the resolution function.

  2. Select the parameters.
  3. Click Apply to complete the configuration.
