Find pattern suffix matching pattern

Code:
Hi,

I am trying to get a result out of this but fails please help. Have two files /tmp/1 & /tmp/hosts. 


/tmp/1
IP=123.456.789.01
WAS_HOSTNAME=abcdefgh.was.tb.dsdc

/tmp/hosts
123.456.789.01

I want this result in /tmp/hosts if hostname is already there dont want duplicate entry.

This is wrong
123.456.789.01 abcdefgh.was.tb.dsdc abcdefgh.was.tb.dsdc

This is correct
123.456.789.01 abcdefgh.was.tb.dsdc

Trying with this:

if grep abcdefgh.was.tb.dsdc /tmp/hosts; then
. /tmp/1 && sed -i "s/^$IP\(.*\)$/$IP\1 $WAS_HOSTNAME/" /tmp/hosts;
fi

Thanks in advance
