Group chat is an important tool used during IETF meetings for real-time discussion and questions, as well as outside of meeting sessions by various groups.


The official messaging platform for the IETF is Zulip, an open source chat and collaboration software.

The IETF operates a dedicated Zulip server and provides individual Zulip streams for all IETF-related groups, including directorates, working groups, and Birds of a Feather (BOF) sessions during meetings and at other times.

Chat is an important aspect of meeting conversations and Zulip streams are integrated into the chat function of Meetecho, which is used for sessions during IETF meetings and many virtual interim meetings organized by individual groups. During meetings using Meetecho, participants can access Zulip either by using the integrated Meetecho feature or via a separate application or Web interface.

Setting up a Zulip account

An IETF Zulip account is needed to access and use the IETF Zulip streams directly, or to message anyone via Zulip. Other Zulip accounts are blocked and prohibited. The IETF Zulip server relies on IETF Datatracker credentials. If you already have an IETF Datatracker account, you can log into the IETF Zulip server using your existing userid and password. If you do not yet have one account, you can create a Datatracker account for free.

Subscribing to Zulip Streams

To send messages to, or view archives for, a particular stream, you must be subscribed to the stream. You can browse streams by name, which typically match the acronym for the IETF group to which it relates. Please note that all stream messages through our servers are subject to the IETF Note Well.

For general chat and nonspecific conversations, subscribe to the IETF Hallway stream. Hallway is the default social chatroom for the IETF. IETF participants often hang out there, and may be able to answer questions and or provide pointers to other resources.
