I wanted to post this answer as an update for users of more recent Android builds  CM11 KitKat 4 4 4   I have not tested any of this with TouchWiz or older Android releases so YMMV   The following commands can be run in all the usual places  ADB  Terminal Emulator  shell scripts  Tasker    List all available properties   getprop   Get WiFi interface   getprop wifi interface   WiFi properties   getprop dhcp wlan0 dns1 getprop dhcp wlan0 dns2 getprop dhcp wlan0 dns3 getprop dhcp wlan0 dns4 getprop dhcp wlan0 domain getprop dhcp wlan0 gateway getprop dhcp wlan0 ipaddress getprop dhcp wlan0 mask   The above commands will output information regardless of whether WiFi is actually connected at the time   Use either of the following to check whether wlan0 is on or not   ifconfig wlan0  netcfg   awk   if   2   UP   amp  amp   3     0 0 0 0 0   isup 1  END  if    isup  exit 1     Use either of the following to get the IP address of wlan0  only if it is connected    ifconfig wlan0   awk   print  3    netcfg   awk    wlan0   sub   0   0   0   0    0-9           3   print  3     Just for thoroughness  to get your public Internet-facing IP address  you re going to want to use an external service  To obtain your public IP   wget -qO-  http   ipecho net plain    To obtain your public hostname   wget -qO-  http   ifconfig me host    Or to obtain your public hostname directly from your IP address    nslookup    wget -qO- http   ipecho net plain     awk    Address 1      if   NF     0 0 0 0    print  NF  exit     name     sub              NF   print  NF  exit    2 gt  dev null   Note  The aforementioned awk command seems overly complicated only because is able to handle output from various versions of nslookup  Android includes a minimal version of nslookup as part of busybox but there is a standalone version as well  often included in dnsutils
