VPCDNS Supported Resolution Record Types

Record Type Description Host Record Description Record Value Description MX Priority Description Weight Description
A Record Points the domain to an IPv4 address. Select a subdomain. For example, for www.123.com, select www. To resolve 123.com, select @. Enter an IPv4 address (e.g., 1.1.1.1). - Weight range: 1–100 (default: 100). Resolution proportion = record weight ÷ total weight of all records for the subdomain.
AAAA Record Points the domain to an IPv6 address. Select a subdomain (e.g., www) or @ for the root domain. Enter an IPv6 address (e.g., 1030::C9B4:FF12:48AA:1A2B). - -
CNAME Record Points the domain to another domain. Cannot coexist with other record types. Enter a subdomain (e.g., www) or @ for the root domain. Enter the target domain. - -
MX Record Points the domain to an email server address. Priority can be set from 1–50; lower value = higher priority. Enter a subdomain (e.g., mail) or @ for the root domain. Domain or IP address of the mail server. Set priority from 1–50. Lower value = higher priority. -
TXT Record Text record (≤255 characters), commonly used for SPF. Enter a subdomain (e.g., www) or @ for the root domain. Free format. Example SPF: "v=spf1 a mx ~all". - -
PTR Record Reverse resolution for an IP address. Only for reverse-resolution domains. For reverse-resolution domain 1.168.192.in-addr.arpa and IP 192.168.1.1, enter 1. Target domain for reverse resolution. - -
SRV Record Identifies a server offering a specific service, e.g., Microsoft directory services. Enter service name and protocol type (e.g., _sip._tcp). Priority, weight, port, and hostname. A dot is added at the end automatically (e.g., 5 0 5269 xmpp-server.l.test.com). - -
SPF Record Specifies authorized mail-sending servers, helps prevent spam. Enter a subdomain (e.g., www) or @ for the root domain. Example: v=spf1 include:spf.mail.test.com ~all — only IPs in A and MX records are allowed to send emails. - -
