Time to live (TTL) determines how long to cache either a query or content. Learn how time to live (TTL) works & how it impacts your website.
Both concepts refer to servers (groups of servers) that are integral to the DNS infrastructure, but each performs a different role and lives in different locations inside the pipeline of a DNS query. One way to think about the difference is the recursive resolver is at the beginning of the ...

In this method, attackers hijack a DNS server configured to return a malicious IP address. By compromising the DNS server, they gain control over the DNS resolution process and can manipulate the responses to redirect users to malicious sites. Exploiting Time-To-Live (TTL): This method exploits...
What is DNS caching? When a DNS client stores DNS records locally, it’s called DNS caching. Caching lets clients produce information about web pages associated with given domain names without having to perform DNS queries. The domain name system also implements a time-to-live (or TTL) on...
DNS is a system for computers and services connected to the Internet that resolves domain names to IP addresses. It converts human readable domain names (www.google.com) into Internet Protocol (IP) addresses (173.194.39.78). Computers can only communicate using series of numbers, so DNS was ...
Akamai is one of the older CDN for live streaming networks. With more than 240,000 servers located in more than 130 countries, it’s also one of the largest. Akamai is one of the oldest CDNs in the world and one of the platforms Dacast partners with. It’s also the most extensive ...
TTL (Time to Live): Each DNS record has a TTL value, specifying how long it should be cached before a new request is made. Lower TTL values result in more frequent updates but higher server load, while higher TTL values reduce server load but may serve outdated information. ...
DNS, short for Domain Name System, helps direct traffic on the Internet by connecting domain names with actual web servers. Learn more in this guide.
However, if no matching IP address is found in your hosts file and cache, other additional steps will be added to the DNS resolution process. What DNS Servers Are Involved in Loading a Website? If your computer can’t find a matching IP address in your hosts file or cache, it will sub...
