Multiple IP addresses - Full Computer Name not getting resolved correctly

P

P1ll3

Hello,

on our servers using Windows 2016 we have two IP addresses.


The Full Computer Name abc.example.com should use the first IP address like 10.0.0.48 and another Name like xyz.example.com the IP address 10.0.0.49.


The ...\etc\hosts file contains two entries like:

10.0.0.48 abc.example.com abc

10.0.0.49 xyz.example.com xyz


nslookup works perectly and resolves the two hostnames correctly to their IP addresses 48 or 49.


But when we do a local ping to the host abc.example.com the ping resolves the name to the second IP address which is just wrong. When we execute ipconfig /flushdns and right after this a /displaydns we see the wrong entries as well but also the correct entries for the second hostname.


Where does this setting come from? Why is the full computer name assigned locally to both IP addresses 48 and 49 doign a local self ping?


Thanks and best regards,

Philippe
