# Network
In this article we will discuss about Networking on Cosmos, how to use the Network Stack, send and received packets. For now, availables protocols are **ARP**, **IPv4**, **UDP**, **ICMP**, **DHCP** and **DNS** but the team is also working on TCP.

All protocols here doesn't support every feature described by their RFC and may have some bugs or architecture issues, if you find something anormal please [submit an issue](http://https://github.com/CosmosOS/Cosmos/issues/new/choose "repository") on our repository.

Each protocol have a Client class wich can be used to receive and send data. If a Receive() method is blocking, the method will timeout after 5 seconds or use the value optionnaly set by parameter. Please note that all finished connections should be closed using Close().

Cosmos Network Stack won't use Classes and Functions that are under .NET Core. Everything described here will be under:
```csharp
using Cosmos.System.Network;
```
Before anything, a Network Configuration must be set (local machine IPv4 address, subnet mask and gateway). It can be manually set with IPConfig.Enable or dynamically set throught a DHCP server. For DHCP, Cosmos will ask to the DHCP server (usually default gateway) for an address in your local network.

### Manually set IPv4 Config

xClient.Close(); //don't forget to close!
```
## DNS
DNS can be used to retrieve corresponse between a domain name and an IP address. For now DNS can only ask for one domain name at the same time.
DNS can be used to get an IP address from a Domain Name string. For now DNS can only ask for one domain name at the same time.
```csharp
var xClient = new DnsClient();
xClient.Connect(new Address(192, 168, 1, 254)); //DNS Server address
