+## High-level overview of [sprint 66][sprint-66]
+
+We held The Network Working Group (NWG) in the last sprint.  Below, we share
+recordings of this and earlier NWG meetings, which introduce basic notions of
+`ouroboros-network`.  These recordings should be accessible to a technical
+audience.
+
+### Introduction to Ouroboros Network, NWG, part 1
+
+```mdx-code-block
+<ReactPlayer controls url='/images/network/NWG-part1.mp4' />
+```
+
+### Introduction to Ouroboros Network, NWG, part 2
+
+```mdx-code-block
+<ReactPlayer controls url='/images/network/NWG-part2.mp4' />
+```
+
+### Tx-Submission
+
+We continued working on the new design of tx-submission.  We progressed in writing
+a new tx-submission server (inbound side of tx-submission protocol)
+instrumented by decision logic.  The next step is writing a simulation that
+runs N-pairs of `client`-`server` communications in which the same decision logic governs all `server`s - emulating the behaviour of `cardano-node` once the new tx-submission is integrated.  For more details, see
+[ouroboros-network#3311]
+
+### Genesis integration
+
+All outstanding PRs related to Genesis have been reviewed and accepted.  Soon
+they will be merged.
+
+* **Big Ledger Peer Targets for Genesis** - [ouroboros-network#4832]
+* **Feed peer selection governor with big ledger peers obtained from a snapshot** - [ouroboros-network#4850]
+* **Introduction of serialization instances in support of ledger peer snapshot** - [ouroboros-network#4851]
+* **Verification of big ledger peer snapshot file** - [ouroboros-network#4888]
+
+### Mithril Integration
+
+We presented ideas on how to run mithril functionalities with
+`cardano-node` while taking into account the risks that such integration would impose on
+the system.  The technical description will be part of a CIP, which will then go to
+the Technical Steering Committee (TSC) for an evaluation.
+
+## Smaller tasks
+
+* **Small improvements and bug fix in the Signal API**, [ouroboros-network#4909]
+* **Improved memory foot-print of tests on ghc-9.8**, [ouroboros-network#4912]
+* **Error cardano-ping whenever there's a decoding error**, [ouroboros-network#4916]
+
+### Open-Source contributions
+
+We found out and fixed a bug in the `iproute` parser of `IPv4` addresses:
+* **Check that IPv4 addresses terminate**, [iproute#63]
+* **IPv4 address with mask should not contain a white space**, [iproute#64]
