How Does TTL Work? TTL's basic function revolves around managing information packets in relation to DNS requests. When one of these packets is created and transmitted through the internet, there is a chance that it will pass, continuously, from router to router forever. To prevent this from...
refreshing it. For example, aDNSserver will have a TTL value for eachrecord, measured in seconds, that controls how long it can serve a record before refreshing it. These TTL entries can be set as low as 30 seconds, but lower-priority records can be set as long as 86,400 seconds (24...
What Does That Mean? You may get a message that says “DNS server isn’t responding” after entering a domain name in the URL bar of your browser. This means there was an attempt to communicate with the DNS server, but the server failed to return a result. This could be due to a...

DNS– depends on the DNS resolver (can range from 128 to 86400) Setting higher TTL values allows packets to traverse more hops before it’s discarded. However, higher values also mean more time is needed before detecting errors. Lower TTL values help detect routing issues faster but reduce th...
NSEC3PARAM (next secure record version 3 parameters): Authoritative DNS servers use this record to calculate and determine which NSEC3 records to include in responses to DNSSEC requests for non-existing names/types. How Does DNSSEC Work? When DNSSEC is used, each answer to a DNS request contai...
DNS propagation is the time it takes updates to DNS records to be in full effect across all servers on the internet.

This data is stored until it's time to live (TTL), which indicates how long content needs to be cached for, expires or the device’s disk or hard drive cache fills up. Data is typically cached in two ways, through browser or memory caching or through CDNs. Browser and memory caching...
