| On POSIX systems, host names may be locally defined in the file <code class="computeroutput"><span class="special">/</span><span class="identifier">etc</span><span class="special">/</span><span class="identifier">hosts</span></code>. |
| On Windows, host names may be defined in the file <code class="computeroutput"><span class="identifier">c</span><span class="special">:\</span><span class="identifier">windows</span><span class="special">\</span><span class="identifier">system32</span><span class="special">\</span><span class="identifier">drivers</span><span class="special">\</span><span class="identifier">etc</span><span class="special">\</span><span class="identifier">hosts</span></code>. |
| Remote host name resolution is performed using DNS. Operating systems |
| may use additional locations when resolving host names (such as NETBIOS |
| names on Windows). |
