sed remove match and next lines -

-

not sure why redgex expression not working, i'm trying ommit match , next lines 

[example.com] 10.0.0.1  10.0.0.2 [example.net] 10.0.0.10 10.0.0.20

desired output 

[example.net] 10.0.0.10 10.0.0.20

here have tried far, matches more lines desired 

   sed -e '/(\[example.com\])(.*\n)+/d'

sed simple subsitutions on individual lines, all. else should using awk every desirable attribute of software (efficiency, clarity, robustness, portability, maintainability, etc., etc.):

$ awk '/^\[/{f=/\[example\.com\]/} f' file [example.com] 10.0.0.1 10.0.0.2  $ awk '/^\[/{f=/\[example\.com\]/} !f' file [example.net] 10.0.0.10 10.0.0.20
