NetStat Agent is a strong and extremely useful network tool for monitoring and diagnosing. It includes all useful network tools such as netstat, ping, traceroute, ipconfig, dns query (nslookup), whois, arp, route and http checker, but in a clean graphical interface.
NetStat Agent allows network administrators to monitor TCP and UDP connections, diagnose connection settings, troubleshoot network configuration, and obtain information about network resources such as remote hosts and domain names. The built-in Whois tool queries domain names for exact information about their owner, and allows checking whether a domain name is taken or still available without visiting any domain registrars Web sites.
A unique feature of NetStat Agent is the capability to change MAC addresses of network adaptors, or restore their original physical MAC addresses if they were changed from somewhere else.
If you need an all-in-one tool to monitor and troubleshoot a network, NetStat Agent is the ideal solution. Featuring comprehensive functionality combined with a full graphical user interface, NetStat Agent will be appreciated by new and experienced Windows network administrators.

Each time when you open a web site in your browser or download files there are TCP/UDP connections are established between your computer and the remote host. Other program also can receive or send information to the Internet. But how can you get the list of all available connections on your computer
We offer an advanced but still quite simple in use the software for monitoring Internet connections and diagnosing network. NetStat Agent is a strong network toolkit that includes well-known tools like netstat, ping, traceroute, ipconfig, arp, route, whois, http checker and dns query (also known as nslookup utility), but in a friendly and convenient graphical interface. It is an extremely useful tool for network administrators and power users.
NetStat
Monitors Internet connections on your computer. It shows the information on all active TCP and UDP connections, local and remote ports, connection states and the owning process.

What is important, NetStat Agent shows the geographical location of the remote IP-address and its hostname. The software contains strong features that allow you to select or hide unimportant connections, close unwanted connection and many more features.
IPConfig
Shows network, adapters and interfaces configuration. IPConfig (Internet Protocol Configuration) allows you to renew DHCP configuration or send the command to DHCP server to release and discard the IP address configuration. This software is very useful on computers that are configured to obtain an IP address automatically.
Ping
This software is very useful for analyzing TCP/IP troubleshoots. It helps to test whether a remote host is reachable across an IP network. Ping is also used to test network configuration of local computer. Ping verifies the host by sending an ICMP echo request and waiting for an ICMP reply. When the reply is received the round-trip time and the geographical location of the remote IP-address will be shown.
TraceRoute
Uses to determine the route between your computer and the remote host. What makes it different from other TraceRoute utilities is the capability to graph the response time and highlight problem hops.

NetStat Agent also shows the geographical location of the hop.
DNS Query
Also known as NSLookup utility that finds all available information about a server including an IP address, mail exchange (MX) records for a domain, authority name server (NS), start of a zone of authority (SOA), domain name pointer (PTR), etc.

Route
Displays and modifies routes in the IP routing table on your computer. The IP routing table helps to detect what interface and gateway will be used to process an IP datagram. This software allows you to add a new route, modify an existing route and delete a route or routes.
ARP
Monitors entries in the Address Resolution Protocol (ARP) cache. NetStat Agent not only provides you with the capability to add new ARP entries or delete an ARP entry in a table, but also enables you to restore the real MAC address, select or hide entries. The software also logs all ARP entries to file.
Whois
Provides you with capability to retrieve all the available information about an IP address or domain such as who is the domain owner and when the domain was registered, administrators and technical support contacts, the geographical location of the internet service provider like country, city, etc.
HTTP Checker
Monitors web sites to test whether an URL is reachable across the Internet. If web site is alive, NetStat Agent will show a status code returned from server. Usually, it is HTTP code "200 OK". The software also shows an IP address of server, country, uptime and the time when the last response from server was received.
Statistics
Shows network and TCP/IP statistics such as received and transmitted TCP segments, maximum number of connections, default IP time-to-live value, a number of ICMP messages, received and transmitted IP datagram's, etc.
