In NetBeans, how do I remove this red line?

I've added the following comment to the start of a java program:
** * * George Tomlinson (I'm not the author). I took this from the
internet and made one correction. * This program converts the string
entered by the user from hexadecimal to ASCII.
*/
The word 'internet' (italicised above but not in the actual program) is
being underlined in red by NetBeans. The error it displays is 'misspelled
word', but it's not misspelled. In Word I would just add it to the
dictionary, but I can't find any such option. Does anyone know how to sort
this out?
