Editing NetBIOS (section)

===Name service===
In order to start sessions or distribute datagrams, an application must register its NetBIOS name using the name service. NetBIOS names are 16 octets in length and vary based on the particular implementation. Frequently, the 16th octet, called the NetBIOS Suffix, designates the type of resource, and can be used to tell other applications what type of services the system offers.{{cn|date=June 2023|reason=Unclear from text what is meant by "octets". Possibly confuses octets with bytes.}} In [[NetBIOS over TCP/IP|NBT]], the name service operates on UDP port 137 (TCP port 137 can also be used, but rarely is).

The name service primitives offered by NetBIOS are:
*Add name – registers a NetBIOS name.
*Add group name – registers a NetBIOS "group" name.
*Delete name – un-registers a NetBIOS name or group name.
*Find name – looks up a NetBIOS name on the network.

[[IPv6|Internet Protocol Version 6 (IPv6)]] are not supported by the NetBIOS name resolution protocol.<ref>{{cite web |title=[MS-WPO]: WINS Management Protocol |url=https://learn.microsoft.com/en-us/openspecs/windows_protocols/ms-wpo/26b6d27b-7470-4a0d-bcfc-88670c6c50d4 |website=learn.microsoft.com |language=en-us |date=14 February 2019 |quote=Because the NetBIOS protocol, defined in [RFC1002], does not support the mapping between NetBIOS names and IPv6 addresses, the Remote Administrative Interface: WINS protocol applies only to IPv4 addresses.
