Since you don't specify which alias to be removed, the lowest IP number is removed. In your case, the lowest IP number happens to be your primary :-) You may want to use the '-alias' command line option to remove an alias: # ifconfig xl0 -alias 172.17.2.3 | Kind regards, Hope this helps, | Spil. - -- Pietro Cerutti gahr@FreeBSD.org PGP Public Key: http://gahr.ch/pgp -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.8 (FreeBSD) iEYEAREKAAYFAkfmZs4ACgkQwMJqmJVx945NsgCg4jfR8JuKsOnGqirAmclnGM80 8Y0AoKeK+mWCGtkniIko2rJlF8UX0EDI =vMXT -----END PGP SIGNATURE-----
