Creating and Configuring DNS Zones and Records

give the reference also

Answer 1

INTRODUCTION

DNS zone is a plain text file that is stored on a DNS server that contain all records for each and every domain given zone. DNS records is used for a particular domain and DNS zone is used for the host. Zone file can accumulate more than 44 different record files , It always start with SOA record.

HOW TO CREATE AND CONFIGURING DNS ZONES AND RECORDS.

There are some steps given below to create DNS Zones and record :

1. we have to open the manager server.

2. Then Click on DNS server.

3. We have to do right click on your server then click on DNS manager.

4. We have to go inside of the DNS manager, Extend your server. extend forward lookup zones.

5. We will have to do right click on your zone and then choose the type of record you that you want to create.

CONFIGURATION

1. You have to go global load balance then Zone tool.

2. Then click ZOne tab.

3. Click on Add to display configure editor window.

4. You have to complete the configured.

Settings Guidelines Name Configuration name. Valid characters are A-Z, a-z, 0-9, _, and -. No spaces. You reference the name in the global DNS policy configuration. After you initially save the configuration, you cannot edit the name. Type Master—The configuration contains the “master” copy of data for the zone and is the authoritative server for it. Forward—The configuration allows you to apply DNS forwarding on a per-domain basis, overriding the forwarding settings in the “general” configuration. FQDN Generate—The zone and its resource record is generated from the global load balancing framework. Domain Name The domain name must end with a period. For example: example.com. Forward Options Forward First—The DNS server queries the forwarder before doing its own DNS lookup. Only—Only query the forwarder. Do not perform a DNS lookup. Note: The internal server caches the results it learns from the forwarders, which optimizes subsequent lookups. Forwarders Select a remote server configuration object. Master Options TTL The $TTL directive at the top of the zone file (before the SOA) gives a default TTL for every RR without a specific TTL set. The default is 86,400. The valid range is 0 to 2,147,483,647. Negative TTL The last field in the SOA—the negative caching TTL. This informs other servers how long to cache no-such-domain (NXDOMAIN) responses from you. The default is 3600 seconds. The valid range is 0 to 2,147,483,647. Responsible Mail Username of the person responsible for this zone, such as hostmaster.example.com.. Note: Format is mailbox-name.domain.com. (remember the trailing dot). The format uses a dot, not the @ sign used in email addresses because @ has other uses in the zone file. Email, however, is sent to [email protected]. Primary Server Name Sets the server name in the SOA record. Primary Server Address The IP address of the primary server. DNSSEC Enable/disable DNSSEC. DNSSEC Algorithm Only RSASHA1 is supported. KSK Filename It is generated by the system if DNSSEC is enabled for the zone. To regenerate the KSK, disable DNSSEC and then re-enable DNSSEC. KSK Type characters for a string key. The file is generated by the system if DNSSEC is enabled for the zone. ZSK Filename It is generated by the system if DNSSEC is enabled for the zone. To regenerate the ZSK, disable DNSSEC and then re-enable DNSSEC. ZSK Type characters for a string key. The file is generated by the system if DNSSEC is enabled for the zone. DSSET Filename The file is generated by the system if DNSSEC is enabled for the zone. The file generated by the zone configuration editor is the one you give to any parent zone or the registrar of your domain. The convention is dsset-<domain>, for example dsset-example.com. DSSET It is generated by the system if DNSSEC is enabled for the zone. DSSET List Select a DSSET configuration object. See Configuring the DSSET list. FQDN Record FQDN Record table Displays a summary of all DNS RR for the zone, including generated and manually configured RR. A/AAAA Record Hostname The hostname part of the FQDN, such as www. Note: You can specify the @ symbol to denote the zone root. The value substituted for @ is the preceding $ORIGIN directive. Type IPv4 IPv6 Weight Assigns relative preference among members—higher values are more preferred and are assigned connections more frequently. The default is 1. The valid range is 1-255. Address Specify the IP address of the virtual server. Method Weighted Round Robin is the only method supported. CNAME Record Alias An alias name to another true or canonical domain name (the target). For instance, www.example.com is an alias for example.com. Target The true or canonical domain name. For instance, example.com. NS Record Domain Name The domain for which the name server has authoritative answers, such as example.com. Hostname The hostname part of the FQDN, such as ns. Type IPv4 IPv6 Address Specify the IP address of the name server. MX Record Hostname The hostname part of the FQDN for a mail exchange server, such as mail. Priority Preference given to this RR among others at the same owner. Lower values have greater priority. Type IPv4 IPv6 Address Specify the IP address. TXT Record Name Hostname. TXT records are name-value pairs that contain human readable information about a host. The most common use for TXT records is to store SPF records. Text Comma-separated list of name=value pairs. An example SPF record has the following form: v=spf1 +mx a:colo.example.com/28 -all If you complete the entry from the the Web UI, do not put the string in quotes. (If you complete the entry from the CLI, you do put the string in quotes.) SRV Record Host Name The host name part of the FQDN, e.g., www. Priority A priority assigned to the target host: the lower the value, the higher the priority. Weight A relative weight assigned to a record among records of the same priority: the greater the value, the more weight it carries. Port The TCP or UDP port on which the service is provided. Target Name The canonical name of the machine providing the service.
