Hammer & Screwdriver Search from 1st match and end 2nd match
I've been looking through the forums for awhile now and looking at the man page for grep and egrep and not seeming to find this scenario so it might not be possible but figured I'd throw it out to get some ideas.

I'm looking for a way to search a file for 1st match (example below net self) and end search when it runs into 2nd match (example below } character) and output those results. Eventually I will want to edit those lines (either delete each line OR replace matching IP Address)

Code:
net self /Common/198.74.92.130 {
    address 198.74.92.130/25
    traffic-group /Common/traffic-group-local-only
    vlan /Common/VLAN221
}
net self /Common/vPC-Interconnect-Floating {
    address 10.47.194.100/27
    allow-service {
        default
    }
    traffic-group /Common/traffic-group-1
    vlan /Common/VLAN233
}
net self /Common/10.47.32.2 {
    address 10.47.32.2/23
    traffic-group /Common/traffic-group-local-only
    vlan /Common/VLAN215
}
net self /Common/10.47.194.40 {
    address 10.47.194.40/27
    allow-service all
    traffic-group /Common/traffic-group-1
    vlan /Common/Interconnect
}

Since I'm far from being knowledgeable but love to learn I have tried what I do know which includes some awful ideas like
Code:
grep ^net self * }

Code:
egrep ‘^net self+}$

Code:
grep ‘^net self.*}$'

I found an example of possibly using awk and tried
Code:
awk ‘/net self/{if (NR!=1)print "";next}{print $0}END{print "";}

xzegrep

XZGREP(1)							     XZ Utils								 XZGREP(1)

NAME

       xzgrep - search compressed files for a regular expression

SYNOPSIS

       xzgrep [grep_options] [-e] pattern file...
       xzegrep ...
       xzfgrep ...
       lzgrep ...
       lzegrep ...
       lzfgrep ...

DESCRIPTION

       xzgrep  invokes	grep(1)  on  files  which may be either uncompressed or compressed with xz(1), lzma(1), gzip(1), or bzip2(1).  All options
       specified are passed directly to grep(1).

       If no file is specified, then the standard input is decompressed if necessary and fed  to  grep(1).   When  reading  from  standard  input,
       gzip(1) and bzip2(1) compressed files are not supported.

       If  xzgrep  is  invoked as xzegrep or xzfgrep then egrep(1) or fgrep(1) is used instead of grep(1).  The same applies to names lzgrep, lze-
       grep, and lzfgrep, which are provided for backward compatibility with LZMA Utils.

ENVIRONMENT

       GREP   If the GREP environment variable is set, xzgrep uses it instead of grep(1), egrep(1), or fgrep(1).

SEE ALSO

       grep(1), xz(1), gzip(1), bzip2(1), zgrep(1)
