Linux not getting data from Windows DNS Server?

Question

linux

There is Ubuntu Server 14.04. It has Zabbix installed. Nodes that work via DHCP are connected to Zabbix.
After the host receives a new IP address, the host is not accessible by DNS name. Under Windows systems, there is a ping, but under Ubuntu Server, the error is, the host is not available. Rebooting Ubuntu Server, dpkg-reconfigure resolvconf didn't change anything.
The problem is that some of the hosts on the DNS records are pinged, some are not.
How to make Linux get DNS records after changing IP on DNS server?

Answer 1

And if you ping by the full name - server.domainname.something ?
If pinged, then in /etc/network/interfaces add dns-search with your domain for the relevant interface.

Answer 2

There is a DNS cache, it has time, usually an hour, but it all depends on the TTL settings on the DNS server. in general it is strangely configured at you why it is impossible to reserve addresses for machines?
Check DNS functionality with the nslookup command.
