When I worked as a server admin at GoDaddy.com ... we would create a second virtual NIC (eth0:1) and configure that with a dedicated IP address that was in the ARIN block they owned. The switches further up the stream would handle the NATing and whatnot to make sure that server got the proper

WOW Thanks!! If we were running a box of VPS's and the box had two NICs would the second NIC be redundant just in case the 1st NIC fails How do multiple NICs on the same box work? OK so the software layer on the O/S talks to the NIC but is not actually assigned to any particular NIC?

Always remember, the network interface from the OS side and the network interface from the hardware side are two completely different concepts. Other than the fact that they are generally matched one to one, they really have nothing to do with one another. A hardware interface (i.e. on a NIC)

Teaming makes multiple Nic's look like one and increases the bandwidth. this ifcfg script will assign to ip's to one nic 192.168.1.8 and 10.1.1.8 TYPE=Ethernet DEVICE=enp6s0 ONBOOT=yes IPADDR=192.168.1.8 NETMASK=255.255.255.0 GATEWAY=192.168.1.1 DNS1=192.168.1.1 PREFIX=24 DEFROUTE=yes

Hi, I'm wondering how VPS servers are configured. I have a VPS with a dedicated IP. I assume I share a box that has a number of virtual machines and I assume each VPS has a dedicated IP. This is a hardware question. I assume the box has at least 2 network cards. So lets say the server
