DNS cache – Definition

Definition of DNS cache

DNS cache is a temporary cache memory that DNS resolvers and other devices utilize to store information. The memory stores the DNS records that were first applied to the searched domain names. The IP addresses (IPv4 or IPv6) of domain names, information about their email server, their services, authentication and verification data, and more are all stored in these records. All of the data will be saved in the DNS cache. However, as previously stated, it will only be for a short time, as determined by the TTL (Time to Live) value issued to each DNS record.

What is DNS spoofing and how to protect yourself?

What does DNS spoofing mean?

DNS spoofing is a form of cybercrime. Criminals insert spoofed or stolen DNS records into a recursive server’s cache. This is due to answering DNS users’ queries with a falsified record, such as a forged IP address. Legitimate traffic is therefore fraudulently redirected to dangerous places (generated websites). Once there, consumers may be compelled to enter sensitive information (passwords, bank credit card details, etc.) for hackers to exploit later.
