Private domain name resolution

Private zone

A private zone hosts a private domain name and record sets for this domain name for domain name resolution. It is applied only to its associated VPCs. You can create, modify, delete, and view private zones, associate private zones with VPCs, and disassociate private zones from VPCs.

• Private zones can be created without the need to register domain names.
• Each private zone must be unique in the associated VPC.

For details, see Overview.

Associating a private zone with or disassociating a private zone from a VPC

You can associate a private zone with a VPC or disassociate a private zone from a VPC.

For details, see Associating a VPC with a Private Zone and Disassociating a VPC from a Private Zone.

Record set

A record set is a collection of resource records that belong to the same domain name. A record set defines the resolution type and value of a domain name. You can add A, CNAME, MX, AAAA, TXT, PTR, and SRV record sets for your private zones. You can also modify, delete, and view record sets.

For details, see Overview.

Wildcard DNS record set

You can add record sets for all subdomains of a private domain name. DNS provides resolution services for all subdomains.

For details, see Configuring a Wildcard DNS Record Set.

TTL

TTL is short for time to live, which specifies the cache period of resource records on a local DNS server, in seconds. The TTL value ranges from 1 to 2147483647.

Batch deletion

You can delete multiple private zones at a time.

Record sets

Global search of record sets

DNS allows you to centrally manage record sets. You can:

• Search for record sets by status, type, name, value, ID, or tag.
• Modify or delete record sets in private zones.

For details, see Searching for Record Sets.

Tag

Resource tagging

You can configure tags for private zones and record sets. You can also use predefined tags provided by Tag Management Service (TMS) to quickly associate tags with resources.

Quota

Quota adjustment

Quotas are enforced for service resources on the platform to prevent unforeseen spikes in resource usage. Quotas can limit the number and capacity of resources available to end users, for example, the maximum number of zones or record sets that you can create.

If existing resource quotas cannot meet your service requirements, you can request higher quotas.

For details, see Quota Adjustment.
