I think they ignore it, but try it to be sure.

Beware.  There are 4 variations on the peers command in ntpq.

The "o" types print the dispersion rather than jitter.
The "l" types print the local IP address rather than the refid.
At least I thought that was what should happen.  lpeers doesn't work that way.

There is also apeers.

These are my opinions.  I hate spam.
