For route table:
$ cat /proc/net/route

For DNS:
$ getprop net.dns1

Hi Joe,

For checking DNS server addresses, you can use getprop, such
as:

| # getprop net.dns1
| 192.168.32.18

or, if you'd like to know the values which dhcp server
offers:

| # getprop dhcp.tiwlan0.dns1
| 192.168.32.18

You also can see dhcp supply default gateway value:

| # getprop dhcp.tiwlan0.gateway
| 192.168.32.1

You might see all property values if you exec 'getprop'
without arguments.

If you'd like to see live routing table, the easiest(but
complicated to understand) way is to see /proc/net/route.

| # cat /proc/net/route
| Iface Destination Gateway Flags RefCnt Use Metric Mask MTU Window IRTT
| tiwlan0 0020A8C0 00000000 0001 0 0 0 00FFFFFF 0 0 0
| tiwlan0 00000000 0120A8C0 0003 0 0 0 00000000 0 0 0

The Destination '00000000' means, of course, default route
and Gateway value '0120A8C0' means '1.32.168.192' in
decimal('192.168.32.1' in reverse), so you can know what is
default gateway address is.

Best Regards,

Hi,

netstat -nr is another way to get the routing table.

Normally yes, except it doesn't work with the "netstat" command on
Android.
netstat -nr just does the same as netstat, namely it lists the open
TCP connections.

# netstat -nr

Sorry, correcting myself, it seems to list all open (IPv4?) sockets,
including UDP sockets and unconnected TCP sockets.

Hi,
is there any guarantee that /proc/net/route works across Android platforms and phones?  I mean, sometimes companies like Motorola decide to apply extra security measures to prohibit developers from accessing useful platform functionalities, like routing tables. 
Does anybody have knowledge about this?

Why not have busybox installed, then you can use busybox route  to get the ip route.
