It's doing exactly what you asked it to do, turn a "binary"
sequence into a string of base 16 numbers spearated by ':'.
That may have been appropriate in the example you copied it
from because in that case it may not have been plain text.
If it's already a text string then just use it as is:
if exists agent.remote-id
log ( info, concat( "DHCPAGENT for lease of ",
binary-to-ascii (10, 8, ".", leased-address), " on agent ",
substring(option agent.remote-id, 2, 6)));
