DNS is a system that matches domain names to IP addresses. It allows people to use names instead of complex IP addresses to find network resources. DNS servers are linked together in a hierarchy of domains. Without DNS, the internet would not be user-friendly. The Domain Name System (DNS) is a computer system that contains […]
DNSSEC is a security extension that authenticates DNS servers and provides data integrity. It was developed by IETF and uses public key authentication techniques. DNSSEC builds trust relationships between different levels of DNS hierarchy to share accurate DNS data. However, zone enumeration and backward compatibility issues arise. DNSSEC implementation began at the root level in […]
Reverse DNS lookup uses the Domain Name System (DNS) to find the domain name associated with an IP address. It can also reveal the owner’s contact information and is used to combat email spam. WHOIS maintains contact information for domain names and IP addresses. To find the Internet domain name associated with a particular Internet […]
DNS cache poisoning is a security weakness where the domain name system provides incorrect information, sending users to unintended locations. It can be caused by malicious attacks or mistakes in configuration and can lead to users being sent to sites containing malicious software. DNS servers are regularly maintained to address any corruption or poisoning. Countermeasures […]
The domain name system (DNS) translates user-friendly names to IP addresses and is used by web browsers to find websites. ICANN oversees the distribution of domain names and IP addresses worldwide. Local networks can have their own DNS systems, and alternative DNS root systems pose a risk to Internet stability and security. Domain name systems […]
DNS hijacking redirects internet users to a different website than the one they intended to visit. DNS servers translate web addresses into IP addresses, but hijacking changes this process to direct users to a different IP address. Hackers can use this technique for phishing attacks, while some ISPs use it for advertising purposes, which has […]
Dynamic DNS is necessary for computers with variable IP addresses to maintain a website or web server without worrying about accessibility. It changes the website’s IP address to keep up with changes in connectivity, eliminating the need to type in the exact numbers of the IP address. Dynamic DNS is available to both personal and […]
DNS translates domain names into IP addresses. It is a network of servers that communicate to find the appropriate IP address. DNS servers can also contain information about other online servers, such as mail servers. Users can bypass DNS by typing the IP address directly. A Domain Name System (DNS) is a service that translates […]
DNS is a system that converts domain names to IP addresses. DNS spoofing is when a DNS address is made to resolve to a different IP address. It can be used for legitimate or illegitimate purposes, including deception. DNS hijacking is different, as it doesn’t necessarily try to trick the user as to the URL […]
Reverse DNS records translate IP addresses into domain names, unlike forward DNS records that translate domain names into IP addresses. They are used for troubleshooting, system monitoring, and anti-spam purposes. PTR records are handled by ISPs, while domain owners are responsible for A records. Matching reverse and forward DNS records can indicate a legitimate domain. […]
DNS redirection, or DNS hijacking, diverts results from a DNS server, often used by ISPs to display a search or help page instead of an error message. It can also block dangerous or illegal websites or be used in phishing attacks. DNS translates a domain name into an IP address, and DNS redirect eliminates the […]
Round Robin DNS assigns multiple IP addresses to alternate responsibility for allowing website users to access the company’s website, lightening server and bandwidth requirements. IP addresses are awarded in a random order, and users see no difference. Round Robin DNS (Domain Name Server) is a creative way to lighten the server and bandwidth requirements of […]
DNS lookup is the process of obtaining an IP address when a DNS resolution request is made. It can travel laterally through the DNS system or be forwarded to ascending or root servers. DNS lookups are used for network tools, email tools, web search, and network security. A Domain Name System (DNS) lookup is the […]
