Invalid IP adress entries in the Properties/Interfaces Tab on windows server 2003 DNS server

When checking my DNS server Interfaces properties i have noticed there are 3 IP addresses entered in the 'Listen On' (see attached image) which i am not aware of. These are the 169.254.62.229, 169.254.182.114, does anyone know what these are and why they have been listed. I did not configure the DN server and these are not listed on the secondary Domain controller/DNS server which i configured?

Also when resolving the IP 192.168.0.54 on our netywork it does not relate to a valid DNS server on our network but has an entry in the DCHP server leases as a remote connection with a unique ID of RAS. Any ideas what could be going on here?

The remaining IP addresses are valid on our Domain controller/DNS server.

The IP 169.254.62.229 & 169.254.182.114

are APIPA address assigned to a nic card, because they are unused NICs - if no DHCP server is available the system will assign that interface an IP within the 169.254.0.0 subnet.

Either disable your unused nic or assign then a static IP adress.

Great Thanks I will disable the unused NICs.

What about IP 192.168.0.54 on our netywork it does not relate to a valid DNS server on our network but has an entry in the DCHP server leases as a remote connection with a unique ID of RAS. Any ideas what could be going on here?

From your DHCP  get the mac address associated with 192.168.0.55 and match it against your DNS server Nics

if you have find a match than this could be a secondary static entry in that Nic cards properties.

if no match is found then you can safely remove it.

By the way are you using  DHCP IP address on server NICs? if yes this is not a good practice.

I am unable to retreive the mac address for the IP 192.168.0.51 as the Unique ID says RAS instead of the mac address, think this is becuase the IP address came from a remote connection (VPN) which is no longer online as i am unable to ping the IP address.

Its really unusual that this IP has been listed in the 'Listen On' properties of the DNS server. Any idea why this would have been added to the list?

We have static IP addresses on the server NICs with resevations on the DHCP server which is good practice yes?

IP address coming  from a remote connection "VPN", that could be one of the probability   .

And yes your IP setup is one of the good practice,

I would also recommend you to follow the securing your DNS server tips from Microsoft
