RFC NetBIOS Naming
RFC NetBIOS Naming is a peer-to-peer naming protocol used by
Microsoft File/Print Sharing that automatically provides hostnames for
devices on networks that support RFC NetBIOS Naming. RFC
NetBIOS naming
uses a six-step process to resolve an IP address for a

Figure 63 DHCP Client Registering a Hostname and PTR Name
1 IP Lease Request
1 IP Lease Request
To begin, the DHCP Client has no IP address and only a hostname that is to be registered. The client
sends a DHCP request to the DHCP server that provides the server with the hostname to be registered.
2 IP Lease Acknowledgement
The DHCP Server responds by sending an IP address and other TCP/IP information to the
DHCP Client. The client now has an IP address as well as a hostname.
3 Dynamic DNS Hostname Update
The DHCP Server attempts to register the newly allocated IP address and desired hostname for
the DHCP Client with the DNS Server.
