Air Route

Air Router is a small utility that lets you show all information about your current network routes. Network routing is the mechanism that allows an iOS device to find the network path to another system.

A route is a defined pair of addresses which represent the “destination” and a “gateway”. The route indicates that when trying to get to the specified destination, send the packets through the specified gateway. There are three types of destinations: individual hosts, subnets, and “default”. The “default route” is used if no other routes apply. There are also three types of gateways: individual hosts, interfaces, also called links, and Ethernet hardware (MAC) addresses. Known routes are stored in the routing table of iOS device.

DEFAULT GATEWAYS
• List the default gateway (router) addresses of active network interfaces.
• Show hostname, network type, MAC address (on Wi-Fi network only), PING capability, WHOIS record for each default gateway.
• Full offline MAC vendor database.

HOSTS AND SUBNETS
• List the known network hosts and subnets.
• Show hostname, network type, MAC address (on Wi-Fi network only), PING capability, WHOIS record for each host.
• Full offline MAC vendor database.
• Show link local and multicast destinations.

ROUTE ENTRY INFORMATION
• Maximum transfer unit (MTU) value.
• Entry expire date.
• Maximum hop count.
• Estimated round trip time (RTT).

INTERFACE DETECTION
• Supported interfaces:
• Local loopback (this device).
• Wi-Fi network (client mode).
• Cellular (wireless WAN) network.
• Bluetooth PAN network.
• VPN tunnel (L2TP, PPTP or Cisco IPSec).
