DNS Best Practices and Its Functions

DNS is a globally scalable, dynamic, hierarchical, and distributed database that gives us the provision of mapping between text records, IP addresses (both IPv6 and IPv4), mail exchange information, hostnames, security key information defined in Resource Records, and name server information. This information is also maintained and grouped into zones in the DNS server so that it can be accessed and globally retrieved through distributed architecture of the DNS. DNS can either use the Transmission Transfer Protocol (TCP) or the User Datagram Protocol (UDP). When the DNS server decides to use the UDP in transportation, it will have the capability to deal with the UDP sequencing and transmission.

Why You Need a DNS Firewall to Protect Your Company Data

The internet doesn’t understand our languages, it communicates in machine languages such as IP addresses. Every time you visit a website with your computer or laptop, the device translates the name of the websites you type into the browser to an IP address. This is made possible by the DNS (domain name system) which resolves human-readable hostnames like the name of a website and translates them to IP addresses. Therefore, no internet connection is possible without a DNS query. Malware isn’t spared either, to steal or corrupt data in your computer, it needs to communicate with its control and command servers which is only possible via the DNS. This is why a DNS Firewall is critical to a DNS server. For more information, the resources at www.bluecatnetworks.com may be helpful to you. » Details
