In addition to identifying packets on the internet, TTL is also used to store information for a certain period of time. Accordingly, CDN (Content Delivery Network) uses TTL to determine how long content is stored in the edge CDN server's cache before a new copy appears and updates to the CDN from the origin server. By setting a reasonable TTL time , CDN can deliver updated content to users quickly without having to continuously send requests to the origin server. This feature helps CDNs deliver content to users quickly, increasing page display speed and reducing bandwidth for the origin server. As for DNS records, TTL is a determined value, used to indicate the time the DNS cache server can remember and store a DNS record before receiving and receiving a new record from the main DNS server.
Regarding TTL, you can learn more about what a CDN is in the article: What is a CDN? Summary of information you need to know about CDN How to create a CNAME record What is TTL? Cname records are often used to create records Loan Phone Number List according to an available value CNAME records are often used to create records according to an existing value In part 1 of the article, you were introduced to the concept of CNAME, what is TTL?. So what is a CNAME record? The CNAME record is used to create a record based on an existing value. If old data is edited, new data will also have corresponding changes. CNAME records also have the effect of authenticating Google's provided services such as: Authenticate domain names and applications Other online services.
To declare a CNAME record, you must have an A record to declare the machine name. At that time, the domain name in the CNAME record will be pointed to the IP address of the Canonical Domain (main domain name). If other domain names want to point to the same server address above, they will be called Alias Domain ("alias" of the main Domain) and will also be declared. For example, you can point blog.mydomain.com, FTP.mydomain.com, mail.mydomain.com to another name mydomain.com. Thus, whichever IP mydomain.com points to, the other names will also point to that IP.
