I have a computer that has one adapter (local network connection) configured for DHCP.
but when I ran the IPconfig /all, it showed several IP addresses and subnet masks for the same adapter.

example:

IP=192.168.200.2
subnet mask :255.255.255.0

IP=192.168.200.5
subnet mask :255.255.255.0

IP=192.168.200.6
subnet mask :255.255.255.0
......
........









Any idea why all those IPs ?

thanks

Do you have virtual servers on the host?

No Virtual server.

This server was configured for DHCP.... Then it stayed offline for a long period of time... then brought back online...
it could be that the lease was expired and got a new IP address ...that would make sense....BUT it should not show all those IP addresses in IPCONFIG /ALL display.


I am trying to check the IP bindings, because sometimes you can bind multiples IPs to one adapter , but don't remember where to check that.

Hi,

go to the network card - > Properties -> IPv4 -> Advanced -> Ip settings

There you have it in the top box :)

if you ping from another server, do you get replies on all IP adresses?

No....
I got reply just from one of them...
I don't know how others are showing up in ipconfig /all
that s not normal, even when the dhcp lease is expired and  the computer has not renewed the ip in time and when it comes back to the network , it might get a different ip than the previous one if the latter is taken by another computer,but ,but,but never seen an ipconfig /all that will show many ip addresses for any reason .

If you check in the DHCP does the server show multiple leases on this server or just a single one.
