tTL 3600 in minutes: DNS TTL Conversion To Minutes and Hours – A guide

TTL is a common acronym in the DNS world but most people do not know how TTL is converted to minutes and hours. For example, people struggle to know what TTL 3600 is in hours, or TTL 86400 in minutes.

In the course of this article, you’ll understand the meaning of TTL and how to easily convert it to minutes and hours.

Also, there is a done-for-you table conversion where you can just get the figure you need for most of the TTLs.

What Does TTL mean in DNS?

TTL stands for “Time to Live” in DNS. It is a value in a DNS record that determines the time frame (in seconds) that a DNS resolver should cache the record before requesting it again from the source.

It helps to reduce the load on the DNS server and improve the overall performance of the network by reducing the number of DNS queries that need to be made.

When a client requests a DNS resolution, the resolver uses the TTL value to decide how long to keep the resolution in its cache before requesting it again.

What’s The Standard TTL to Use?

The standard TTL value to use can vary depending on the specific use case and the type of DNS record.

For example, for a DNS record that is likely to change frequently, such as the address of a web server, a low TTL value of around 60 seconds or less is typically used. This allows for quick updates to the record in case of any changes.

For DNS records that are less likely to change, such as the address of a mail server or the name servers for a domain, a higher TTL value of several hours or even days is commonly used.

This allows DNS resolvers to cache the record for a longer period of time, reducing the number of queries that need to be made.

In general, the best practice is to use the lowest TTL value that will still provide the desired level of performance.

It is also important to consider the potential impact of changes to the DNS records on your users and to coordinate changes with them to minimize any disruption.

How TTL is Converted To Minutes and Hours

TTL is typically measured in seconds, so in order to convert it to minutes or hours, you would simply divide the TTL value by the number of seconds in a minute (60 seconds) or an hour (3600 seconds).

To convert TTL to minutes, you can use the following formula: TTL (in minutes) = TTL (in seconds) / 60

For example, if the TTL value is 1800 seconds (30 minutes), you would divide 1800 by 60 to get 30 minutes.

To convert TTL to hours, you can use the following formula: TTL (in hours) = TTL (in seconds) / 3600 seconds.

For example, if the TTL value is 86400 seconds (24 hours), you would divide 86400 by 3600 to get 24 hours.

It’s worth noting that these are rough estimates and are not always accurate. In practice, the actual time a DNS resolver holds a query in its cache can be slightly different from what the TTL value suggests.

Conclusion

In summary, TTL 3600 in minutes is 60 minutes or 1 hour, 14400 TTL in minutes is 240 minutes or 4 hours, and TTL 86400 in minutes is 1440 or 24 hours or 1 day.

My recommendation for TTL is to use the lowest value that will still provide the desired level of performance.

It’s also important to consider the potential impact of changes to the DNS records on your users and to coordinate changes with them to minimize any disruption.

The best practice is to keep the TTL value as low as possible for records that are likely to change frequently, and higher for records that are less likely to change.

It’s also important to be aware that TTL is typically measured in seconds, so it can be converted to minutes or hours for better understanding, but the actual time a DNS resolver holds a query in its cache can be slightly different from what the TTL value suggests.
