Well, it is possible to add lots of rows in one operation with the SQL
command "COPY" (read Postgres' documentation) but running 2000 INSERT
queries on such type of table doesn't take a long time, since you seam
not to have lots of columns in your table ip_list.
Even if you have an index (unique or not) on one of the columns of
your table it won't be really time-consuming.
In my database I have a table with 350000 rows and inserting new rows
is very fast with the insert command (altougth it would be faster with
COPY - but COPY is usually used for data transfers with text files).
