Yes.

To achieve this you will have to use regular expressions.
You'll need to filter on
123\.456\.789\.\d{1,3}
and turn on 'Regular expressions' in 'Options' tab of filter.
The '\' escapes the wildcard '.' to be a real period and the trailing
'\d{1,3}' searches for a combination of digits form 1 to 3 characters
long.
So '123.456.789.SOS' will not be matched, while both '123.456.789.1'
and '123.456.789.762' will.
'123.456.789.123123980' would be matched too as you did not specify
what should be after the last tripel. To be sure it's only IP-style
you'll have to use
123\.456\.789\.\d{1,3}\D
What tells the filter it should search for '123.456.789.' followed by
1 to three digits, followed by a non-digit. That does not prevent you
form catching senseless IP's like
'123.456.789.698' as you have no chance to validate the number is
between 0 & 255 (including), but it's quite sure better than nothing :-)
