If the /etc/hosts file has multiple entries of the same IP address, each one with different aliases, the local DNS page will only show the last entry of that IP address, hiding from the user some other aliases that address could have.
This only happens if the /etc/hosts file is modified by hand and manually add the "duplicated" IP entries. Like in my case, I found the problem when I copied over the hosts file of one of my servers which has one IP address per alias, it was written that way for readability. I know that the hosts file man page says that there should be only one entry per IP address but in practice it allows multiple lines.
I'm attaching a little patch that fixes this behavior on the local DNS page, displaying only one IP address and all its aliases no matter how much times that address is listed in the hosts file, and when updating the host in the local DNS page, it saves only one lline per IP address with all its associated aliases.
