HINFO Records

What are HINFO Records?

HINFO records are system information records used to provide a definition of the hardware and operating system in use at a host. For security reasons, these records are rarely used on public servers.

How to Configure HINFO Records

1.Select Managed DNS and click on Domains

2. Select the Domain Name you want to add an A record too.

3. Under the HINFO Records section, click the  plus_icon to add a record.


A) Name: This will be the host name for the record, typically a computer or server within your domain.

B) TTL: The TTL (Time to Live) in seconds is the length of time the record will cache in resolving name servers and web browsers. The longer the TTL, then remote systems will lookup the DNS record less frequently. Your name servers will also receive less query traffic since most queries are answered by resolving name servers. Conversely, the shorter the TTL the faster any changes you make to your DNS will propagate in servers that have cached data. However, your domain will receive more query traffic.

C) CPU: A description of basic system hardware. Identifiable name of the CPU you want to point the record too.

D) OS: A description of the operating system and version

E) Notes: Add a helpful note with keywords so you can search for your records later.

F) Save: Save your record changes and don’t forget to Commit Your Changes after you’re done making record changes for this domain!

Recommended values:

Records that are static and don’t change often should have TTL’s set between 1800 (being on the low end) to 86400 seconds (30 minutes to 1 day cache).

Records configured with Failover or that change often should have TTL’s set anywhere from 180 to 600 (3 to 10 minutes cache).

If a change is needed for a record with a high TTL, then the TTL can be lowered prior to making the change and then raised back up again after the changes were made.
