  • Page 42: Configuring Dynamic Ip Address

    DHCP is the default setting. If you specify a hostname for the CodeWarrior TAP probe, the probe will attempt to register the host name with the DHCP server, which may then update any name servers on the network.

  • Page 43: Static Routing

    The simplest networks consist of one or more subnets. Routers forward network traffic from one point on the network to another across these subnets. If the CodeWarrior TAP probe uses DHCP to automatically acquire its network settings, it is most likely that a default gateway setting was acquired and the probe will be accessible on other subnets.
