Overview
VPCDNS is a private DNS management service for the Virtual Private Cloud (VPC) environment. It allows you to map private domains to specific IP addresses in one or more custom VPCs.
With VPCDNS, you can easily create, delete, and modify private domains, manage VPC bindings, and support adding, deleting, and modifying records. These private domains cannot be accessed outside of the VPC. Moreover, you can connect your VPC to a traditional data center via methods such as dedicated lines or VPNs, allowing resources to be accessed mutually through private domains between the traditional data center and your Converge Cloud VPC.
Product Features
Private DNS
The private domain list contains the private domain resource records that you need to manage. You can create multiple private domains that you want to use and add the following types of resolution records for them:
| Record Type | Description |
|---|---|
| A | It is used to specify the IPv4 address (for example 8.8.8.8) of a domain. If you want to point a domain to an IP address, you need to add an A record. |
| AAAA | It is used to specify the IPv6 address (for example ff06:0:0:0:0:0:0:c3) of a domain. If you want to point a domain to an IPv6 address, you need to add an AAAA record. |
| CNAME | Alias record. It points to another domain. |
| MX | If you want to set up your mailbox so that it can receive emails, you need to add an MX record. |
| TXT | You can enter anything in this record with a length limit of 255 characters. Most TXT records are used as SPF records (for anti-spam). |
| PTR | It reversely maps an IP address to a domain. |
| SRV | It is used to identify that a server is using a specific service, which is commonly found in the Microsoft system's directory management. The format is Service Name. Protocol Type, such as _sip._tcp. |
| SPF | Used to specify mail-sending servers. It's an efficient anti-spam solution. |
Associating with VPC
You can associate a private domain with one or more VPCs that need to be configured so as to map it to IP addresses.
Description
Private domains with the same name cannot be associated with the same VPC. For example, when two
example.comexist at the same time, it is not possible to associate bothexample.comwith the same VPC.
Reverse Resolution
Reverse DNS refers to mapping an IP address to a domain; that is, the private domain pointed to by the IP address is obtained by querying the PTR record of the IP address.
Subdomain Recursive Resolution
When the subdomain recursive resolution setting is enabled, subdomains not configured will automatically be forwarded to the default recursive domain server for resolution.
Custom Private Domain
It plans CVM hostname management to make machine use and information more understandable and user-friendly.
Internal API Call
API calls are managed internally to avoid the troubles caused by IP address changes to the API use, which makes ops easier.
Internal Domain Security Isolation
The core system privacy protection feature ensures that the domain of internal core systems is not exposed to the Internet and thus improves their security.
