DNS Q&A

QWhat are the differences between the free and paid versions of DNS resolution?

The paid version includes Professional and Business editions. The paid packages offer higher and more comprehensive configuration capabilities, delivering higher quality resolution services. And they also include availability SLA guarantees. For more info, please refer to the comparison chart on this page.

QHow to choose a suitable DNS resolution package?

The free version of the DNS resolution service is available for free usage. Startups or individuals with requirements for stable resolution and traffic routing are recommended to use the Professional edition. Users with higher demands for resolution quality are recommended to choose the Business edition.

QHow to fill in the DNS record?

A: Address record, used to specify the IPv4 address of a domain (e.g., 8.8.8.8). If you need to point a domain to an IP address, you need to add an A record.

CNAME: If you need to point a domain to another domain, which then provides the IP address, you need to add a CNAME record.

MX: If you need to set up email and receive emails, you need to add an MX record.

TXT: You can enter anything here, with a length limit of 255 characters. The majority of TXT records are used for SPF (anti-spam) records.

NS: Name Server record, used to delegate subdomains to other DNS service providers for resolution. You need to add NS records.

AAAA: Used to specify the IPv6 address (e.g., aa51::c3) corresponding to a hostname or domain. Resolves to an IPv6 address.

SRV: Records which computer provides a particular service. Format: service name, dot, protocol type, for example: _xmpp-server._tcp.

CAA: Certification Authority Authorization for verification. Format: flag, tag, value.

QHow to change domain name resolution to IP or alias?

To change the resolution to an IP address, you need to modify the record type to A and enter the IP in the record value. If you need to resolve to an alias, you should change the type to CNAME. Type A corresponds to IPv4, type CNAME corresponds to alias records, and AAAA corresponds to IPv6 addresses.
