"Fast flux DNS" is a technique used by hackers to make it difficult to track and shutdown their websites and other online resources. The term "fast flux" refers to the way in which the hackers change the IP address associated with their domain name very rapidly - often every few minutes - making it hard for authorities to track down the real location of their servers. This technique is often used in conjunction with other methods of hiding their tracks, such as using multiple domain names and "botnets" (networks of infected computers).
What is double IP flux technique?
The double IP flux technique is a method used to detect and block malicious traffic on a network. It works by monitoring the flow of traffic to and from a given IP address, and comparing it to a baseline of normal traffic activity. If the traffic to and from an IP address exceeds a certain threshold, it is considered suspicious and is blocked.
This technique is particularly effective at detecting and blocking distributed denial of service (DDoS) attacks, as they typically involve a large amount of traffic from many different IP addresses.
What is DNS tunneling?
DNS tunneling is a technique used to encapsulate data within DNS queries and responses in order to bypass network filters or firewalls. This technique can be used to tunnel any type of data, but is commonly used to tunnel traffic that would otherwise be blocked by a firewall, such as Internet traffic.
DNS tunneling works by encoding data within the DNS queries and responses. The data is then decoded by the tunneling software on the receiving end. This allows the data to bypass any network filters or firewalls that are in place.
DNS tunneling is a relatively simple technique and can be easily detected by network administrators. However, it can be difficult to block, as legitimate DNS queries and responses must be allowed through the firewall.
If you are concerned about DNS tunneling on your network, you should consider implementing a DNS firewall. This will block all DNS queries and responses that do not originate from a trusted DNS server.
Is botnet a malware? Botnets are networks of computers infected with malware that allow attackers to control them remotely. Although botnets can be used for legitimate purposes, such as distributed computing or managing large networks, they are often used for malicious activities, such as launching denial-of-service attacks, stealing data, or sending spam.
What is DNS round robin technique?
DNS round robin technique is a method of load balancing that is used to distribute traffic across a number of servers. This technique is often used by web hosting companies to distribute traffic to their customers' websites across a number of servers.
The DNS round robin technique works by returning a different IP address for each DNS query. For example, if a user types in www.example.com, the DNS server will return the IP address of the first server in the round robin. The next time the user types in www.example.com, the DNS server will return the IP address of the second server in the round robin. This continues until all of the IP addresses in the round robin have been returned, at which point the DNS server will start again at the first IP address.
The main advantage of the DNS round robin technique is that it is simple to set up and does not require any special hardware or software. Additionally, this technique can be used to distribute traffic across servers in different geographic locations, which can help to improve website performance for users who are located far from the server.
There are a few disadvantages of the DNS round robin technique. First, this technique does not take into account the different capacities of the servers that are being used. As a result, some servers may end up receiving more traffic than they can handle, while other servers may have spare capacity. Additionally, the DNS round robin technique does
