IPv4 Routing

IPv4 routing and various IP addressing features are supported. This chapter describes the basics of 
domain name service (DNS), address resolution protocol (ARP), and routing principles and their 
implementation in the Dell Networking OS.

IP Addresses

The Dell Networking OS supports IP version 4 (as described in RFC 791), classful routing, and variable 

length subnet masks (VLSM).

With VLSM, you can configure one network with different masks. Supernetting, which increases the 
number of subnets, is also supported. To subnet, you add a mask to the IP address to separate the 
network and host portions of the IP address.
At its most basic level, an IP address is 32-bits composed of network and host portions and represented 
in dotted decimal format. For example, 00001010110101100101011110000011 is represented as 
10.214.87.131.

For more information about IP addressing, refer to RFC 791, Internet Protocol.

Implementation Information

You can configure any IP address as a static route except IP addresses already assigned to interfaces.

NOTE: 31-bit subnet masks (/31, or 255.255.255.254), as defined by RFC 3021, are supported. This 
feature allows you to save two more IP addresses on point-to-point links than 30-bit masks. The 
system also supports RFC 3021 with ARP.
