iNet Pro
find out what's going on
in your network ...
iNet Pro is a collection of tools to provide you with information about the networks your iPhone or iPod touch ist connected to. Its very easy and user friendly design allows even for the unexperienced user to get a profound and understandable overview of his network and the running services.
What is the difference between iNet and iNet Pro ?
Comments on iNet at The Unofficial Apple Weblog TUAW
Scan network
iNet shows the devices connected to your local network, e. g. computer or router, along with their name, IP and vendor. You can find out the name, vendor and IP of the connected devices as well as the kind and number of running Bonjour services on that particular device. You can also perform a classic portscan on the choosen device.
The technology used in iNet scans on a very low level, therefore you even find machines that don`t want to be found, e. g. a computer running in stealth mode.
Most items are displayed by their real name so that you can easily identify what is going on in the network you are scanning, which computers are connected or which services are running. For most Apple Macintosh Computers you even see the particular computer model.
The last 10 scan results are saved automatically. In addition you can save your scan results and name them. A send scan per mail is available too.
Ping
Ping is a computer network tool used to test whether a particular host is reachable across an IP network. The ping section in iNet enables you to find out wether an IP exists (if its ping service is enabled; otherwise you will get no response :-)). For your convenience we added a bookmark function to store often needed addresses.
Bonjour-Browser
Bonjour or "zero configuration networking" is a widely used industry standard for connecting computer and computer devices ,e.g. printers. The Bonjour-Browser in iNet scans the connected local network for Bonjour services, detecting any hardware that ist connected via the Bonjour protocol (e. g. computer, router, printer, …) and any software running Bonjour services, e. g. iTunes® or Filemaker®.
Wake on lan - sleep on lan
WOL is a wakeup tool for computer connected by an ethernet cable or by wifi to a local network or to the internet. iNet can set Macintosh computers to sleep or shutdown (this feature for Windows devices in still in development). The outstanding feature of our implementation is its easiness of usage and the simple setup process. A bookmark function for often used hosts is integrated also. For more information see iNet WOL, the stand-alone tool for WOL.
Portscan
Applications on devices communicate with the outside world through so called TCP-Ports. iNet detects whether ports are open or closed.
A quick portscan is available after performing a network scan. Here iNet checks TCP ports in the range of 1 to 1000 plus a number of standard ports that are often used.
A sophisticated portscan is available via the main menu of iNet. You can select from predefined portlists, enter port ranges and single ports. The ports to scan can be saved per device. For all found open ports the service using this port is displayed by its real name if available.
Device info
The device info in iNet shows some information related to your iPhone or iPod touch, e. g. its name or its IP.
iNet help
All features iNet performs are described in more detail in the help section.
For wake on lan we provide additional setup guides here: WOL Setup Guide and Comprehensive WOL Setup Guide.
More in development
The modularisized structure of iNet allows to add more features and scanning methods in the future. We will implement by time more network monitoring tools, e. g. DNS-Querys, Traceroute, Whois lookup etc..

What iNet does
This explanation is aimed at technically experienced people.
The “Scan network” functionality is the most complex part of iNet. First the current IP address of the iPhone for the WiFi interface is determined. If this IP address is self-asigned (169.254.x.x), iNet performs a ping to the multicast broadcast address. If we are in a “normal” IP environment the class C subnet range is pinged one by one.
After pinging, the ARP table of the iPhone is queried to get all MAC addresses of machines on the subnet. If a device shows up in the ARP table, but did not reply to our ICMP echo request, the device is marked as hidden. Via the “MAC address vendor prefix” the computer vendor for a particular device (respectively its network interface) is found out.
At the same time we do an “all services” Bonjour query. If a service is found it gets resolved and is assigned to the corresponding host from the ping/ARP-Table results. Every resolved service is queried for an _device-info record. This way we get the specific device model string for Apple computers. The _device-info record for a host is only present if certain services are available (e. g. AFS, VNC, AirportBaseStation), so not all Macs get resolved into their model.
Reverse IP lookups (hostnames) are performed as unicast and multicast queries for every IP found.
Via a IP packet with a TTL of one we determine the router in the subnet that grants access to the internet, if possible.
Although we did a lot of testing, by the complex nature of networking in general we need your feedback to improve our scan engine.

iNet Revision History
Since our initially release iNet has evolved quite a lot. This follows our philosophy that iPhone apps deserve the same kind of support, ongoing development and update strategy that is common for desktop applications. We think that iPhone apps are not bound to be limited 99ç "spinoffs" of desktop apps. We want to evolve iNet towards a tool that directly competes with desktop solutions for network scanning. The inherent design paradigms of the iPhoneOS actually help to really focus on what kind of information and user interaction is needed at a given time.
The next update for iNet will bring us much closer to our goals. Here is a quick overview of iNet develoment:
