  • Question

  • I got a quick question in regards to IP address and computer name on the network. When I do a ipconfig on my computer via command prompt on my computer connected to the company network, I get my ip address say 10.3.40.158.

    When I do a nslookup of my computer name, it shows the correct ip address 10.3.40.158.

    But, the weird thing is when I do a nslookup of the ip address 10.3.40.158, it shows a different computer name and not my computer name.

    Is it because maybe the IP address is now distributed to me now, but maybe it just haven't refreshed in the DHCP?

  • This is quite common and you are right, its because the DNS hasn't been refreshed and shows the old host name it was initially registered to.

     

    I have a similar case as well. I been allocated a bunch of IPv4 and IPv6 addresses. The IPv6 are natively allocated and will resolve properly in either way (reverse or not). But 5 of my IPv4 were previously used by someone else and he/she used his own DNS servers to resolve them. Now I use them natively. I don't use any registered DNS server to handle them.

     

    So, if you do a DNS look up on my domain name, it will resolve correctly to the IP address but if you do a reverse DNS, it will point to a different domain name.
