3Com Router WL-537 User Manual

How does a Device Obtain an IP Address and Subnet Mask?115
This type of IP Address operates on a subnet mask of ‘255.255.0.0’.
See an example about how a network (only four computers represented) 
and a Router might be configured.
IP Addressing and Subnet Masking
How does a Device 
Obtain an IP 
Address and Subnet 
Mask?There are three different ways to obtain an IP address and the subnet 
mask. These are:
■Dynamic Host Configuration Protocol (DHCP) Addressing
■Static Addressing
■Automatic Addressing...

116APPENDIX B: IP ADDRESSING
Automatic IP addressing is a scheme  where devices allocate themselves 
an IP address at random from the industry standard subnet of 
169.254.x.x (with a subnet mask of 255.255.0.0). If two devices allocate 
themselves the same address, the conflict is detected and one of the 
devices allocates itself a new address. 
Automatic IP addressing support was in troduced by Microsoft in the 
Windows 98 operating system and is  also supported in Windows 2000.
