Hi Neo,
Are you suggesting that I should create short name alias for potentially every name that is absent in DNS ? Note that "ServFail" happens for absent records.

You can either create an entry in /etc/hosts or as a CNAME in your DNS (but in DNS, you must type the domain name, not a single "short name" without the domain name.
Without visibility into your DNS, it's hard to tell what your problem is and if you would post the exact domain name it would be easier to help you debug and so post the FQDN and we can look it up on the Internet.
But, just to give you one example of a real server name on the Internet, like www.unix.com.
Even me, I cannot type www to get to www.unix.com unless I put an entry in my /etc/hosts file.
That is how the Internet works. DNS needs domain names. It is the "DOMAIN NAME SYSTEM".
If you want to use a short word alias, you need to use /etc/hosts. That is how the Internet works.
If I wanted to type "icecream" and to to this site, I would then have this:
What am I missing here? This is how it has always worked, as far as I can remember. DNS needs domain names. If you want a short single word alias, you need an /etc/hosts file entry, or so that is how I have always done it.
Like I said, maybe I'm missing something, LOL But this is how I have always done it.... and never had a problem in big and small orgs/networks/domains.

Also, to be clear, I am not saying it is not possible there is another way to do this beside /etc/hosts.
What I am saying is that I have been doing this for many decades (since before the Internet was commercial), and some orgs I have worked as their lead network systems engineer are very huge, and everyone types the FQDN to get to hosts, routers, hubs and switches on network, and when they want or need short one name aliases, we always use /etc/hosts and we have never had a problem, ever.
Maybe I'm just a "simple" kind-of-guy because I like to keep things simple and so they work cleanly and without problems.
If you have 100 servers or 200 and they all need one word "short cuts" to get to a FQDN, just create one file and distribute it to all who need it. That is how we have always done it.
I guess some try the "append it automatically", but frankly, I have seen that method (many years ago) have problems, so that is not how we did it; so I'm telling you want works, for sure. Sometimes keeping things simple works very good
I think I have failed to articulate the problem. Let me try again.
The client, in the first attempts, append the domainname (as it is in the resolv.conf). If the record is not found then it tries again -- this time it drops the domainname. How do I stop the 2nd attempt or dropping of the domain?
The tcpdump when the above command was run:
Please observe that the domain name , biman.net has been appended only in the first appempt
biman.net is the domain name. "shortname" does not exist neither as a DNS record , nor as device's name. I am just explaining how DNS client is behaving when query is made for a non-existent record
