What is the DNS code for Cisco Open?

Cisco Open is the brand name used by Cisco for their new range of routers that use open source software (OSS) and which are based on the Juniper router model. The Cisco Open web site is currently hosted at cisco.com but will soon be transferred to a web site controlled by the developers of the Open Source Network Operating System (OSNOS), the operating system which is being used by Cisco in their new range of OSS routers.

The OSS routers will be able to run the same software as the Cisco routers that they replace, so the DNS server code will need to support both Cisco and OSS routers. However, I think it would be more appropriate to host the code at the main open source router web site (). This would allow the software to be maintained by the community rather than by Cisco. The DNS code is very similar to that used by Juniper, so the developers at Juniper will also be able to update the code fairly easily.

I have asked the OSS project managers whether the code should be hosted at the Juniper web site or at the OSS web site, and they have indicated that it is preferable that it be hosted at the OSS web site. It is only going to be a minor change so it should not cause any problems. However, the DNS code does need to be changed to match the new web site structure, so the DNS code may need to be updated.

The DNS server software will need to support any type of DNS server and the DNS server configuration will also need to be able to support any type of configuration. I'm happy to update the existing DNS code to support Cisco Open and it will probably be necessary to make some changes to the DNS server configuration in order to handle the Cisco Open configuration.

Can you provide a little more detail about what this code is doing? For example, are you talking about the code that handles host name lookups? Is this for all protocols? If so, I think this should be implemented by a higher level program, like libreswan/libresolv. Or is this just host name lookups? This code was previously written for the Cisco 7000 router, and is called the Domain Name Service Server (DNS).

What is DNS server in Cisco?

Answer: DNS server has many terms like DNS Server, DNS Cache Server, DNS Client Server.

A DNS server serves the resolution of domain name to IP addresses by providing a look up table.

Answer: DNS is responsible for translating domain names into IP addresses. If you do not own a domain name, you have to have a DNS server (also called Domain Name System or DNS Server) at your home or office and register it with one of the public DNS service providers like or They provide you with a free dynamic DNS service so that your IP address will always change with each new request. You can create a URL link to any site of your choice and point it to the DNS server's IP address.

Answer: The process of converting the human readable domain name to an IP address is known as DNS, which stands for Domain Name System. As per Cisco's data sheet, it stands for the following.

Answer: A DNS (or domain name system) allows users and devices on the internet to communicate by referencing IP addresses. In other words, it is a network protocol used to resolve names of computers or networks on the internet. A user's web browser communicates with a DNS server for Internet access and DNS server resolves the browser's request to a host's IP address. When this address is requested the browser communicates with the ISP for the final destination address.

Answer: Domain Name System (DNS) is a naming and addressing system that is used to locate computer resources on a network. Dns is used to translate domain names into IP addresses. It can be used to address a single computer or multiple computers. One of the major functions of the DNS is it maps your domain name to your IP address. For example, when you type a search query in google, its web browser requests a search for a particular word. Google's servers are responsible for the search query and they reply back with a list of relevant websites. However, it is much more than just searching for webpages; it is also used to locate other resources including FTPs, Gopher and file transfers.

Answer: Domain Name System is basically a protocol used for locating resources on a computer network. When you visit a website, it uses the DNS server to translate the domain name into IP addresses.

Which DNS servers are public?

My ISP does NOT control DNS on my network.

My clients use a combination of external DNS servers and the ISP DNS server. So far I have configured it to use both external and ISP DNS servers but my question is what DNS servers are public?

Is this in any way harmful or illegal or is it just an academic question? Re: DNS servers are public? Wouldn't you use your own DNS if you could? Originally Posted by vinnyc. And here I was, all smug and self-righteous and now I can't find it. But then, I had to switch to Win 8 and that always makes finding things hard. And when I do find something it's gone.

It seems to me that my server will fail without my dns servers being available. The problem is, I don't have any control over my clients' DNS servers and I want to be able to send any user trying to visit them a failure message if they aren't in my own DNS pool. What's the correct way to accomplish this?

Thanks for the responses. I guess I didn't think about the difference between public and private dns. In any case, it sounds like I don't need to make any changes to how my server works if the list of DNS servers is public. This is an interesting question - and one that I've never really thought about before. A question I'm interested in would be to ask 'why don't we use our own DNS servers on our home networks?'
