In "/etc/netsvc.conf" you specify the precedence in which the various possible sources for name resolution are being used. The entries after "hosts=" are used in the order they appear in this list. What you see as "hang" is probably the source queried first not knowing about the host. This source will have to time out before the next source in the list is queried.
That means: suppose you want to resolve the name of some host "host.at.your.domain" and the content of your "/etc/netsvc.conf" is
which would mean the system looks in its "/etc/hosts" file (=local) first and only if this fails will query the DNS server (bind). If "/etc/hosts" doesn't hold an entry about "host.at.your.domain" it will look up this, wait for the timeout, only then ask the name server.
Have a look at your "/etc/netsvc.conf" file and determine which source of information has precedence. Then investigate if this source is able to answer the query for a certain IP address.

RESOLVER(5) File Formats Manual RESOLVER(5)NAME
resolver - resolver configuration file
SYNOPSIS
/etc/resolv.conf
DESCRIPTION
The resolver configuration file contains information that is read by the resolver routines the first time they are invoked by a process.
The file is designed to be human readable and contains a list of name-value pairs that provide various types of resolver information.
On a normally configured system this file should not be necessary. The only name server to be queried will be on the local machine and the
domain name is retrieved from the system.
The different configuration options are:
nameserver
followed by the Internet address (in dot notation) of a name server that the resolver should query. At least one name server should
be listed. Up to MAXNS (currently 3) name servers may be listed, in that case the resolver library queries tries them in the order
listed. If no nameserver entries are present, the default is to use the name server on the local machine. (The algorithm used is
to try a name server, and if the query times out, try the next, until out of name servers, then repeat trying all the name servers
until a maximum number of retries are made).
domain followed by a domain name, that is the default domain to append to names that do not have a dot in them. If no domain entries are
present, the domain returned by gethostname(2) is used (everything after the first `.'). Finally, if the host name does not contain
a domain part, the root domain is assumed.
The name value pair must appear on a single line, and the keyword (e.g. nameserver) must start the line. The value follows the keyword,
separated by white space.
