Avoid a warning by new versions of grep and really filter out empty lines #68

When searching for ASN information using a newer version of grep, you get two warnings intermingled with the output: "grep: warning: stray \ before n". I'm assuming the grep -Ev "^\n" was used to filter out empty lines. Changing this to grep -Ev "^$" get rid off the warning and really filters out empty lines.
