Combine awk statements

I have an awk statement that works but I am calling awk twice and I know there has to be a way to combine the two statements into one. The purpose is to pull out just the ip address from loopback1.
Code:
cat config.txt | nawk 'BEGIN {FS="\n"}{RS="!"}{if ( $0 ~ "interface loopback1" ) print$4}' | nawk 'gsub(/\/32/,""){print $3}'

Sample config:
Code:
!
interface loopback0 loopback
 description test1
 ip address 10.30.133.5/32 tag 100
  ip source-address tftp ftp
!
interface loopback1 loopback
 description test2
 ip address 10.159.1.5/32 tag 101
!
interface loopback2 loopback
 description test3
 ip address 10.159.1.170/32 tag 102
  ip source-address radius
!

Code:
nawk 'BEGIN {FS=RS;RS="!"} /interface loopback1/{split($4,a, OFS "|/");print a[4]}' config.txt

That works perfect, thank you! Except I messed up and did not realize that my ip address line may not always be $4, it could be on any line in that record. This works for me but again I am calling awk up too many times.
Code:
cat config.txt | nawk 'BEGIN {FS="\n"}{RS="!"}{if ( $0 ~ "interface loopback1" ) print$0}' | nawk '{if ( $0 ~ "ip address") print$3}'| nawk 'gsub(/\/32/,"")'

Code:
nawk 'BEGIN {FS=RS;RS="!"} /interface loopback1/{for(i=1;i<=NF; i++)  if ($i ~ /ip address/){split($i,a, OFS "|/");print a[4]}}' config.txt

Code:
awk -F'[ \/]' '/interface loopback1/{getline;getline;print $4;exit}' config.txt
