What is Local DNS? Introduction Local Domain Name Service (DNS) is a system that assigns domain names to machines connected to the internet. Every device on the internet has an IP address, which is a unique set of numbers identifying it. However, IP addresses can be hard to remember and can easily be mistyped. Local DNS resolves this by associating a domain name to an IP address. It also makes websites more accessible by linking domain names to web servers. Therefore, humans tend to use domain names when referring to machines on the internet. Local DNS is a service that is run by your ISP that takes in domain names and translates them into IP addresses when requested. This makes it easier to remember domain names and often speeds up the time it takes to access a website. What is Local DNS? Local DNS is a service of the data center. The data center has servers that have information about the website. When the user wants to visit a site they type in the address into their web browser, then it gets sent to the server, and then sent back to the user's screen. This process is the same for every single user, but local DNS changes that. Local DNS is a program that takes the website name, then finds the IP address of that website. It takes that IP address and sends it to the server for use by all of the users in the data center. Local DNS will change the IP address of a site that users within a certain location cannot access. The data center then gives the IP its own IP and lets users in to visit whatever site they want. This also makes it safer for people to browse sites because their IP addresses will be changed so other countries cannot trace them. Many companies use local DNS to provide faster and more stable service to their customers, including Google and Comcast. One major disadvantage is that your connection can be censored because you're using a server for your area. How does it work? Local DNS is a cloud-based system that enables the web service to be accessible even in cases where the internet connection has been interrupted. A user is not required to sign in to make a connection. However, it may be necessary for the user to provide some credentials when they are trying to access content from any geo-specific server that is owned by the company. Local DNS servers take logs of local websites that users visit and then pass them over to the cloud-based system. This makes it possible for the system to determine which information should be made available to users in each region. The company can then manage each region's DNS to ensure that the information users receive is accurate. What are the benefits of Local DNS? Some of the benefits of using a local DNS include:- - more stable connection because it relies on your wifi or cellular. - faster internet speeds because it only caches content for your location - less loading time due to more speed and fewer hops, since it's just looking at nearby servers. - less data usage. You can save money by using a local DNS. - more privacy because the content is looking for nearby servers that is local to your location. - better security from the man in the middle intercepts - fewer ads without having to block them, since they're only delivering cached content in your location. What are the disadvantages of using Local DNS? The primary disadvantage of using local DNS is that it does not provide global connectivity. Local DNS will only provide a connection to resources in the same network. The secondary disadvantage of using a local DNS is that it does not work with programs such as Skype, which require their own set of DNS servers. The third disadvantage of using local DNS is that it cannot be used on an IPv6 network. Local DNS is also more susceptible to spoofing, which occurs when a false IP address appears in the logs of a system. This is because many attacks come from users with spoofed IPs, making it very difficult to determine malicious activity. Conclusion Local DNS is a type of DNS system that only caches the addresses of resources on your local network. This means it won't be able to resolve any names outside your LAN. To make this work, you'll need an application running locally on each computer in order to get access to external resources. Applications like these are called proxy servers and can redirect traffic from one server or domain name to another without requiring changes by the user at their end. The benefits of using Local DNS include increased speed when browsing near-local sites, less bandwidth usage for remote connections, and improved security with many applications not exposed directly over the internet (making them more difficult targets). The disadvantages would be if you're trying to browse something that's hosted remotely but doesn't have a proxy service available, you won't be able to access the page.
