comment Order of search for name resolution in Unix/Linux
About having the dot as the first entry in the search (ie: "search ."), it doesn't work for me. In fact with dot present in the search domain resolver is not sending out the absolute query at all.

comment Order of search for name resolution in Unix/Linux
Thanks. I am running ubuntu 14.04. Setting ndots:0 triggers an initial absolute query. If that fails the resolver does continue and tries with the other search domains. But I am wondering if this behavior is consistent since you observed your resolver not trying other search domains if the first one fails. What *nix/resolver are you using ?

comment VM migration and IP address
I accepted your answer. I should have worded the question differently because what I wanted to know mainly was how important the IP stability is from application point of view.

comment VM migration and IP address
Tagging vmware-esxi was a mistake. I removed it. And my previous comment about libvirt was just to clarify that retaining the same IP could depend on features provided by the management/orchestration software. Bottom line, what I was trying to understand was how important is it that the service's IP remain the same from an application point of view.

I understand its hard to answer this without the application specifics. In the case of Vmotion do you know if the TCP sessions are also maintained across a migration ?

Probably the DHCP wasn't a right example. Correct me if I am wrong here, In the case of KVM, for VM migration libvirt does some work behind the scenes to make sure the UUIDs of the interface remain the same after the migration. My understanding is this helps the software like Nexus 1000v or Nuage to assign the same interface policies and config (which includes IP as well)

IP address need not be a VM OS level setting. It could be from a DHCP server. So a higher level entity like a VM management software is involved typically to make sure the IP doesn't change.

No, I am not particularly interested in VMware. My intent is to understand how important it is for the clients that the service's IP doesn't change.
