A DNS (Domain Name System) is a system that translates Internet addresses into a meaningful name. The most commonly used DNS services are the ICANN (Internet Corporation for Assigned Names and Numbers), and the freed DNS (Digital DNS). The ICANN offers free services and also requires customers to register with them. The free D DNS is operated as a provider’s service where it registers domain names for user searches.
Any request to a DNS server needs a reply and this is done by getting a reply from the DNS server. The reply includes the IP address of the server that will return the requested information. DNS services are usually used by internet access providers such as internet cafes, cable companies, and telecommunication companies. It is also used by subscribers of the USA Internet Telephony Conference and Video Registrations (USIP). In addition, some ISP’s use their own internal proxy to solve DNS conflicts.
There are a number of ways to configure a DNS proxy. You can either do it manually or by using an easy-to-use configuration tool. For more information on how to configure a DNS proxy, see Internet Help: Configuring Your Internet Connection.
A potential problem can occur if you already have an existing configuration that uses the default gateway associated with your ISP (e.g. the host computer). If this is the case, a common problem that can occur is that the default gateway used by your ISP is not functional or has a security flaw. To resolve this, you need to update the firmware on your router, or, if your modem cannot accept firmware updates, then you should contact your ISP and ask them to upgrade your gateway.
Another potential problem that arises from a failed or faulty proxy setup is an inbound ingress interface. An inbound ingress interface is basically where your system sends its request for data to another location, which it expects will be able to deliver the requested data. If the other location cannot deliver the requested data in the format that you expected, then your system will retry the request until it can obtain the IP address or domain name that was originally requested. If this happens, you may see a message similar to the following:
“Cannot configure dns proxy dns requests. The server did receive an inbound request, but no domain name or IP is available. The reason is that the server forwarding the request did not receive a response that satisfies the query. The best way to solve this problem is to make sure that you have one or more servers responding to inbound requests. To configure the server forwarding of these requests, use a program like ICQ or WebEx to create a local area network (LAN).
A single IP address can be used to configure several dns servers if the number of IP addresses that are configured is large enough. However, you need to configure at least three dns servers in order to use a single IP address to configure multiple dns servers. When you first set up a single IP address, all the other IP addresses associated with that single IP address will have an IP address of zero (or an IP that is subnetted to that IP address).
Now you should be able to understand why the above example is important and what you need to test to ensure that your VPN is working. If you are not sure how to do this, then you should follow the below instructions to enable dns proxy in Azewa workspace. Once you have enabled dns proxy in Azewa workspace, you should be able to access the internet in the location of your choice.
