The advantage for internal use is the possibility to use the DNS to label links, like: 10.0.0.1 my.side.of.the.link.to.my.provider 10.0.0.2 his.side ... looks neat :-) -- -[ Philippe Regnauld / regnauld@eu.org / +55.4N +11.3E @ Sol3 / +45 33241690 ]- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
