NSLookup Different addresses for Alpha and Numeric

[quincer]

Hi I was wondering if it was a firewall item when I :
1.look up an alpha address which will return a numeric address.
2.look up the numeric address I get a completely differnt alpha address.
3.look up the alpha address I get IP address or host name not found.

Is it a firewall? Or a multihomed system perhaps?

=(

Perhaps the address you are resolving to a certain IP is just a temporary dynamic address. Addresses can point anywhere to any IP but IPs need to have one and only one address that it resolves to as to which network resource it belongs.

There are redirectors out there that can point to your IP so that you can use these redirectors easier than your IP or normal resolved name. But the resolved name and IP are your actual network information.

This is not considered "Multi-homed" this term means a machine has more than one IP that it hosts. This usually only happens in a server enviroment and if you were to ping or nslookup each IP they would have their own corosponding address. and each of these IPs could in turn have redirectors pointed at them too.
