DVIPA

[edit]

Sometimes referred to as VIPA - Virtual IP Address or DVIPA - Distributed VIPA

Multiple addresses

[edit]

"A server IP address depends on the MAC address of the attached NIC, and only one logical IP address may be assigned per card.": wrong. A NIC can respond to any number of IPs. Remote hosts use to ARP protocol to determine which MAC use for any given IP. The opposite is true however: an IP address can be bound to a single MAC address only. — Preceding unsigned comment added by 81.7.230.226 (talk) 14:37, 25 November 2013 (UTC)[reply]


I concur. Ethernet adaptors can be bound to many mac addresses and IP addresses, at the same time (as far as a user is concerned)

Example: multiple ip addresses on 1 adaptor:

2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000

   link/ether e7:0f:22:57:03:5e brd ff:ff:ff:ff:ff:ff
   inet 192.168.255.248/28 brd 192.168.255.255 scope global eth0
      valid_lft forever preferred_lft forever
   inet 172.16.30.1/23 scope global eth0

Examples of multiple MAC addresses on 1 adaptor, see VirtualBox

Improvements

[edit]

I've edited the page substantially, to

  • provide an actual definition, rather than defining it as one of the applications
  • deleting the incorrect statement referred to above
  • clarifying the text (hopefully)
