Q. Can one Linux / BSD system respond to multiple IP address on a single Ethernet interface? I need to run multiple web sites and mod_ssl with a single server. How do I configure my box for multiple IP address?
A. Linux / UNIX and BSD like operating systems supports multiple IP address on a single interface using a feature called ip aliasing. You can add extra IP addresses with the ifconfig command. However, I recommend modifying configuration files so that operating system remember all ips after reboot.
See our previous FAQ and How-tos about IP aliasing:
- FreeBSD Setup 2 IP address on One NIC ( IP alias )
- How to bind a range of IP’s in Debian / Ubuntu Linux
- Red Hat / CentOS / Fedora Linux add multiple IP address
