We've been over this before. Your "search host dns" line doesn't do
anything at all as written, but will screw things up if copied in a
different order by someone who doesn't know that it's simply broken.

That still doesn't specify what IS wrong. Reading the now 5+ year old man
page, the only change I might make is to change the dns string to
nameserver. IP changed host to hosts too.

What man page? Honestly, it seems like you're making things up at this point.

Might be "man resolv.conf".

Can't be, that man page clearly says:

      search Search list for host-name lookup.
             The search list is normally determined from the local domain name; by default,
             it  contains  only  the local domain name.  This may be changed by listing the
             desired domain search path following the search keyword with  spaces  or  tabs
             separating  the names.  Resolver queries having fewer than ndots dots (default
             is 1) in them will be attempted using each component of  the  search  path  in
             turn until a match is found.  For environments with multiple subdomains please
             read options ndots:n below to avoid man-in-the-middle attacks and  unnecessary
             traffic for the root-dns-servers.  Note that this process may be slow and will
             generate a lot of network traffic if the servers for the  listed  domains  are
             not local, and that queries will time out if no server is available for one of
             the domains.

It certainly doesn't say anything about putting "host" or "dns" or "nameserver" in that line.
