Use a DHCP server for dynamic IP address or a fixed IP address if the PC and
web server are integrated on an existing LAN. Contact your network administrator
about the fixed or dynamic IP address to be used. You can change the LAN
settings via the local operation of the web server. Details see section 10.
Configure the IP address on the PC network settings or web server so that the PC
and web server are on the same network. In the example above, the PC must have
a static IP address 192.168.1.xxx (with xxx of 1 and 254, but NOT 110) and the
network mask must be set to 255.255.255.0.
The following IP addresses are reserved for private networks:
 Class A: 10.0.0.0–10.255.255.255.
 Class B: 172.16.0.0–172.31.255.255.
 Class C: 192.168.0.0–192.168.255.255 (typical for home networks).
To access web server, enter the web server IP address (e.g. https://192.168.1.110)
in the browser (Chrome, Safari, Firefox).
For additional information on web server settings and operation over the browser,
see section 12.
Additional information on router configuration is available in the Appendix, page
123.
