HTTPS Record Generator

Automatically tries to detect and generate a fitting HTTPS record for any website.

What is a HTTPS record and why do I need it?

An HTTPS record is a specialized form of the Service Binding (SVCB) DNS record. These records enhance the flexibility of secure internet connections, making them more reliable and faster. Here are the key points:

• Purpose:

  HTTPS records provide detailed information about services available for a specific domain. They play a crucial role in establishing secure network connections like HTTPS by providing essential details.

• Efficiency:

  Unlike traditional methods that involve multiple round trips between the client and server, HTTPS records streamline the process. They reduce the number of round trips required to establish a connection, enhancing efficiency.

• Security:

  By fetching necessary parameters via a single DNS query, HTTPS records minimize security risks associated with multiple queries or connections.

Configuration Example

Domain:

Record:

www.sample-test.com. 1800 IN HTTPS 1 .
alpn=h3,h3-29,h2
ipv4hint=1.2.3.4,9.8.7.6
ipv6hint=2001:db8:3333:4444:5555:6666:7777:8888,2001:db8:3333:4444:CCCC:DDDD:EEEE:FFFF

Elements:

• alpn=h3,h3-29,h2: Specifies supported application protocol versions.
• ipv4hint: Optional IPv4 addresses.
• ipv6hint: Optional IPv6 addresses.

By leveraging HTTPS records, browsers efficiently obtain complete instructions for accessing a website, including supported protocols, IP addresses, port numbers, and public keys, all in a single query.
