  • DNS and BIND 5e
    DNS and BIND 5e

    DNS and BIND tells you everything you need to work with one of the Internet's fundamental building blocks: the distributed host information database that's responsible for translating names into addresses, routing mail to its proper destination, and even listing phone numbers with the new ENUM standard. This book brings you up-to-date with the latest changes in this crucial service.The fifth edition covers BIND 9.3.2, the most recent release of the BIND 9 series, as well as BIND 8.4.7. BIND 9.3.2 contains further improvements in security and IPv6 support, and important new features such as internationalized domain names, ENUM (electronic numbering), and SPF (the Sender Policy Framework).Whether you're an administrator involved with DNS on a daily basis or a user who wants to be more informed about the Internet and how it works, you'll find that this book is essential reading. Topics include: * What DNS does, how it works, and when you need to use it * How to find your own place in the Internet's namespace * Setting up name servers * Using MX records to route mail * Configuring hosts to use DNS name servers * Subdividing domains (parenting) * Securing your name server: restricting who can query your server, preventing unauthorized zone transfers, avoiding bogus servers, etc. * The DNS Security Extensions (DNSSEC) and Transaction Signatures (TSIG) * Mapping one name to several servers for load sharing * Dynamic updates, asynchronous notification of change to a zone, and incremental zone transfers * Troubleshooting: using nslookup and dig, reading debugging output, common problems * DNS programming using the resolver library and Perl's Net::DNS module

  • DNS of Wall-Bounded Turbulent Flows : A First Principle Approach
    DNS of Wall-Bounded Turbulent Flows : A First Principle Approach

    This book highlights by careful documentation of developments what led to tracking the growth of deterministic disturbances inside the shear layer from receptivity to fully developed turbulent flow stages.Associated theoretical and numerical developments are addressed from basic level so that an uninitiated reader can also follow the materials which lead to the solution of a long-standing problem.Solving Navier-Stokes equation by direct numerical simulation (DNS) from the first principle has been considered as one of the most challenging problems of understanding what causes transition to turbulence.Therefore, this book is a very useful addition to advanced CFD and advanced fluid mechanics courses.

  • What is DNS?

    DNS, or Domain Name System, is a system that translates domain names into IP addresses. It acts as a phone book for the internet, allowing users to access websites and other online services using easy-to-remember domain names instead of complex numerical IP addresses. DNS plays a crucial role in the functioning of the internet by facilitating the communication between devices and servers.

  • Which DNS server?

    The DNS server is a crucial component of the internet infrastructure that translates domain names into IP addresses. There are different types of DNS servers, including authoritative DNS servers, recursive DNS servers, and public DNS servers like Google DNS or OpenDNS. The choice of DNS server depends on factors such as speed, security, and reliability, so it is important to select a DNS server that meets your specific needs.

  • What is the meaning of primary DNS and secondary DNS?

    Primary DNS and secondary DNS are both part of the Domain Name System, which is responsible for translating domain names into IP addresses. The primary DNS server is the first point of contact for a device trying to access a website or service, and it is responsible for resolving domain names into IP addresses. The secondary DNS server acts as a backup to the primary server, and it is used if the primary server is unavailable or experiencing issues. Having both primary and secondary DNS servers helps to ensure reliable and redundant access to websites and services on the internet.

  • What is the significance of primary DNS and secondary DNS?

    Primary DNS and secondary DNS are both crucial components of a domain name system (DNS) setup. The primary DNS server is the first point of contact for translating domain names into IP addresses, and it is responsible for hosting the authoritative DNS records for a domain. The secondary DNS server acts as a backup to the primary server, ensuring redundancy and improving the reliability and availability of the DNS service. Having both primary and secondary DNS servers helps to distribute the DNS query load, provide failover support, and prevent downtime in case the primary server fails.

  • What is spatial visualization ability?

    Spatial visualization ability refers to the capacity to mentally manipulate and comprehend spatial relationships between objects. Individuals with strong spatial visualization skills can easily visualize and understand how objects relate to each other in space, such as rotating or manipulating shapes in their mind. This ability is crucial in various fields such as engineering, architecture, and mathematics, as it allows individuals to solve complex problems and understand spatial concepts more effectively. Improving spatial visualization ability can enhance problem-solving skills and overall cognitive performance.

  • Is spatial visualization important for engineers?

    Yes, spatial visualization is important for engineers as it allows them to mentally manipulate and understand complex 3D objects and structures. Engineers often need to design and analyze various components and systems, and spatial visualization skills help them to conceptualize and communicate their ideas effectively. Whether it's designing a new product, creating blueprints for a building, or solving complex problems, spatial visualization is a crucial skill that allows engineers to think critically and innovate in their field.

  • Does DNS break in heat?

    DNS (Domain Name System) itself does not break in heat. However, the physical infrastructure that supports DNS, such as servers and networking equipment, can be affected by high temperatures. If these components overheat, they may malfunction or shut down, causing DNS services to be disrupted. It is important for organizations to have proper cooling systems and backup plans in place to prevent DNS outages during periods of high heat.

  • What is a private DNS?

    A private DNS is a Domain Name System (DNS) server that is used exclusively within a private network, such as a company's internal network. It is used to resolve domain names to IP addresses within the private network, allowing devices within the network to communicate with each other using domain names. Private DNS servers are not accessible from the public internet, providing an added layer of security and privacy for the internal network. Organizations can customize and manage their private DNS servers to meet their specific needs and requirements.
