If you can ping 8.8.8.8 but you cannot ping www.Google.com then what is the problem?
If you can ping 8.8.8.8 but not www.google.com, the issue likely lies in DNS resolution. Your network can reach the Google Public DNS server (8.8.8.8) directly, but it may not be able to translate the domain name www.google.com into its corresponding IP address. This could be due to a misconfigured DNS server, connectivity issues with the DNS service, or problems with the local DNS cache.
What is Forwarders and Root Hints?
Forwarders and root hints are mechanisms used in DNS (Domain Name System) to resolve queries. Forwarders are DNS servers that receive queries from clients and forward them to another DNS server for resolution, typically used for efficiency and centralized management. Root hints, on the other hand, are a list of IP addresses of root DNS servers that a DNS server can use to start the resolution process when it cannot find the answer locally or through configured forwarders. Together, they help ensure that DNS queries are resolved accurately and efficiently.
What is a conditional forwarder?
A conditional forwarder is a DNS server configuration that allows a DNS server to forward queries for specific domain names to designated DNS servers. This setup is useful in scenarios where an organization needs to resolve names in a different domain without fully integrating the two networks. By specifying which domains to forward and to which servers, organizations can streamline DNS resolution and improve efficiency for cross-domain queries. Conditional forwarders help maintain separation between different network environments while still enabling necessary communication.
What is Use of inverse domain?
Inverse domain is used to map an address to a name. For instance, if a server receives a request from a client and this server has only the ip addresses of the clients in its list then the server needs to find out if this client is on its authorized client list. In order to determine if the client is on the authorized client list,server asks its resolver to query to the DNS server to map an address to name. And this type of querys are called inverse query(pointer query -PTR).
What is meant by domain?
Domains is a group of computers and other resources that are part of a network and share a common directory database .Once a server has been installed , you can use the Active Directory Wizard to install Active Directory in order to install Active directory on the first server on the network , that server must have the access to a server running DNS (Domain Name Service). If you don't have install this service on your server then you will have to install this service during the Active Directory installationThe 'domain' is simply your computer address not to confused with an URL. A domain address might look something like 211.170.469.A Domain is simply a name with which we use to refer a computer.It mean online property!The domain is the "end part" of the Uniform Resource Locator (URL) of an Internet address. It identifies a subdivision of the net so that the location of an individual, group or organization can be pinpointed.Domains include: .com, .net, .gov, .edu, .mil, .uk, .fr and a whole bunch more.Other meaningsDomain has more than one meaning. It can mean a place under one rule or one control, or it can mean a sphere of influence or control. In mathematics, it means the set of possible values of an independent variable. In physics, it means a discreet region of magnetism in ferromagnetic material. Finally, if you add an e at the end to make the word Domaine, then it means a vineyard.
When does DNS replication take place?
DNS replication typically takes place automatically and continuously whenever changes to DNS records are made. This ensures that the updated information is spread across multiple DNS servers, providing redundancy and improving the availability of DNS services.
Where can one find information on dns made easy?
DNS Made Easy is a solution for business to setup a DNS and own multiple domains. DNS Made Easy information is best obtained through their website that has plan information.
What is the difference between an open DNS and a closed DNS?
There is one major difference between an open DNS and a closed DNS. Open DNSs allow multiple users to connect easily while closed ones do not allow more users.
What is the point of using a dns service provider?
In this case they host the DNS rather than just registering your domain name. Look for on with multiple locations for the best service.
What is a DNS Revolver used for?
The client side of a Domain Name System (DNS) is called a DNS Resolver. It is responsible for initiating the queries that lead to the full resolution of the translation of a domain name into an IP address. A small amount of DNS Resolvers only communicate to one single server instead of multiple servers.
Who is the one person that controls the World's DNS?
Because there are multiple root level servers no one person or organization controls the DNS for the world. It is also a distributed system so this would not be possible.
Where can one find information DNS load balancing?
DNS load balancing is defined to be spreading the load of people on a certain website accross multiple survers if one does not suffice. One can find more information about DNS load balancing on sites like Zytrax and Splux.
Where would one find details on what is DNS?
HTG (how to geek), is possibly the top site for technical related questions and how-to guides. Regarding this question specifically, they have a fairly in-depth article explaining what exactly DNS is.
Why would multiple DNS Servers be listed?
Multiple DNS servers are listed for redundancy and reliability. If one server fails or becomes unreachable, the system can still resolve domain names using an alternative server, ensuring continuous access to services. Additionally, having multiple DNS servers can help balance the load and improve response times for users by routing queries to the least busy server. This setup also enhances security by reducing the likelihood of a single point of failure.
What is dynamic DNS integrated DNS?
The dynamic DNS integrated DNS refers to the method of automatically updating a name server in the DNS in real time.
Does DHCP or DNS lead to network connectivity problems?
It can if the administrator of the DHCP server has input incorrect values. DHCP is to provide a device with answers to commonly asked questions that it will need to correctly function in a network. If you can't get a DHCP address and everybody else can the problem is on your end most likely.
Which functions might be included on a DNS server?
A DNS server typically performs functions such as resolving domain names to IP addresses, caching DNS queries to improve response times, and providing authoritative answers for specific domains. It may also support reverse DNS lookups, where IP addresses are translated back into domain names. Additionally, DNS servers can implement security features like DNSSEC to protect against certain types of attacks and can manage zone transfers to synchronize data between servers.
