Show interface/ip using awk

ifconfig -a| awk '/^wlan|^eth|^lo/ {;a=$1;FS=":"; nextline=NR+1; next}{ if (NR==nextline) { split($2,b," ")}{ if ($2 ~ /[0-9]\./) {print a,b[1]}; FS=" "}}'
Interfaces like lo can be omitted from the beginning, there are probably better ways of doing this, i'm a noob at awk.
Sample Output
lo 127.0.0.1
wlan0 192.168.1.100
