Research of method for DNS performance. - Keio University.
The Domain Name System (DNS) is used to map easy to remem- ber hostnames to Internet Protocol (IP) addresses in the Internet. When a user enters a URL in the browser window its cache is first.
Design of a Dual Stack DNS Server with Dynamic Updates Olaleye Oludare, Olaniyan Ayodele, Famuyiwa Kolawole. Abstract- The need for dynamic reconfiguration of IP addresses increases mostly due to the increased mobility among internet connected devices. A previous research work was able to develop a solution for dynamic DNS with updates initiated by the client based on already available.
The use of a rogue DNS server is a very serious threat to all users of the internet as the information contained on a rogue DNS server might not be safe. A rogue DNS server can be used enable a malicious user to attack a host machine or network by the use of DNS spoofing or host name spoofing. A rogue server is essentially a server that lies.
A DNS server is a computer server that contains a database of public IP addresses and their associated hostnames, and in most cases serves to resolve, or translate, those names to IP addresses as requested. DNS servers run special software and communicate with each other using special protocols.
Consider a resolving DNS server pool with two servers labeled A and B. Server A receives a DNS request from a host, and finding it has no cache entry for the destination, recursively sends a request to an authoritative server. The authoritative server, in turn, sends a challenge to the IP address of server A. This address, however, is an anycast address assigned to the entire pool of recursive.
DNS is a fundamental core technology of the Internet as we know it. It allows users to find websites easily and removes the requirement to know the IP address of every single host on the Internet. This paper will discuss two attacks on DNS and will show how an attacker can control your traffic.
An Introduction to Managing DNS 5.4m views. by Justin Ellingwood,. Bind is an extremely flexible DNS server that can be configured in many different ways. In this guide, we will discuss how to install Bind on an Ubuntu 14.04 server and configure it as either a caching or forwarding DNS server. Leveraging a DNS server configured like this can help speed up DNS queries for client computers.
