Let me show you a very simple way to improve your website’swebsite’s reliability – Anycast DNS. You can have multiple DNS servers with the same IP address and speed up your domain resolution greatly. Here is how.
Why should you care about DNS?
DNS is the system that makes it easy for all of us to use the Internet. It translates the domain names to their IP addresses. That way, it distributes queries to the right places. For example, if you search for Google.com, your browser will have the task of using DNS to search for the correct DNS server and find the IP address of Google so that you can connect to it. In a traditional scenario, a single Primary DNS server will answer all queries for a domain name. But you can improve that by having multiple servers which can answer the query. So here comes the Anycast DNS.
Keeping the operation of a business healthy and competitive requires a lot of control. Monitoring services for businesses are the trustable and sharp allies you need to keep track of and analyze every detail of your company’s performance.
Monitoring services are important because they provide the following:
IT, just like online businesses, require to supervise constantly their software and hardware to keep everything running without problems. Downtime, failures, and lack of efficiency can prevent your business from reaching its goals. Prevention, detection, diagnosis, and fixing are vital tasks that can be improved if you get visibility.
DNS and its security (DNSSEC) are critical topics for online businesses.
What is DNSSEC?
Domain Name System Security Extensions, or DNSSEC, is a group of security measures created to provide cryptographic authentication to DNS data. It checks and proves the integrity of DNS data so you can be sure they haven’t been altered.
Network experts commonly describe it as a chain of trust because it verifies every point in the process a DNS query follows.
A Secure Shell Fingerprint (SSHFP) record is a resource record that specifies the SSH keys connected with a host/ domain name. In addition, this provides remote connection log and networking services over an untrusted channel. When a public key is not identified, we use the Secure Shell Fingerprint record. Additionally, it will be kept locally and used for connection validation in the future.
