two public ip addresses on one interface

[Andrei Manescu]

Hello,

If I want to put two public IP addresses, with different subnetmasks (my ISP is changing some subnets and for two months I will be able to use two public ip addresses) on the same interface (xl0) my rc.conf shuld look like this:

ifconfig_xl0="inet 84.125.210.108  netmask 255.255.252.0"
ifconfig_xl0_alias0="inet 81.66.10.36 netmask 255.255.255.255" (this ip address has mask /24 )

or is there any other possibility to have two ip addresses on the same nic, besides aliases ??


Thank you in advance.
