Not how it works here on a 5209R: (fairly new load)

cat /etc/hosts
# /etc/hosts
# Auto-generated file. Please put your customizations at the very end.

# Entries for localhost and primary IP address:

# Entries for all other IP addresses bound to this server:

<primary-ip>.133                  jweb2.<fqdn>                 jweb2
<primary-ip>.100                  jweb2.<fqdn>                 jweb2

<primary-ip>.130                  jweb2.<fqdn>                 jweb2

# END of auto-generated code. Customize beneath this line.


With line 42 commented out, the "all other IP addresses" section
is not there leaving just the vsites and the server itself.
