Time-to-Live (TTL)
The DNS System powers the internet as we know it today and is responsible for converting domain names into IP addresses and for placing them on the correct hosting server. But the DNS system would have been just a theoretical concept, if TTL was not presented.
TTL is an acronym for Time To Live and refers to the capability of the DNS servers to cache DNS records. It represents the amount of time that a DNS record for a certain host remains in the cache memory of a DNS server after the latter has located the host's matching IP address.
By specifying TTL settings for a particular domain's DNS records, webmasters define the frequency of website content updates. The longer the TTL value is, the faster the domain resolution time periods will be. The TTL value can be set from one to several hours, if you are not planning any changes to your domain's DNS records in the meantime. If you need to make such changes, you will have to decrease the TTL value entry to several minutes to avoid any outdated data on your website.
TTL values are entered as seconds and the common TTL time value is 86400 seconds, which is virtually equal to one day (24 hours). With this value set for your domain, any changes to your DNS records will be reflected online in up to 24 hour
