delete dhcp.conf entry using sed

I am trying to use sed to remove entries from my dhcpd.conf file.

The form of the file is:

host foo {
        option 1
        option 2

host bar {
       option 1
       option 2

I was trying to use a label like:

 sed -e :a -e "s/^host bar {[^}]*//g;/{/N;//ba" /etc/dhcpd.conf

I want to delete every from "host bar" to the "}".

Any thoughts?
