Manipulating with pfctl

Tables can be manipulated on the fly by using pfctl(8). For instance, to add
entries to the table created above:

# pfctl -t spammers -T add 218.70.0.0/16

This will also create the table if it doesn't already exist. To
list the addresses in a table:

# pfctl -t spammers -T show

The -v argument can also be used with -Tshow to display statistics for each
table entry. To remove addresses from a table:

# pfctl -t spammers -T delete 218.70.0.0/16
