Enable IPv6 support
Description
Enable IPv6 in nim-libp2p end-to-end so users of the library can run dual-stack when needed. Scope covers transports (tcp/quic), address handling (multiaddr, identify), and ci/test infra.
Task List
Core transports (tcp/quic)

Description
Add IPv6 listen/dial for tcp and quic. Might require changes in chronos
Deliverables
- nodes can listen on /ip6 and accept inbound requests
- dialer can dial /ip6 addresses
addresses & identity

Description
Add IPv6 support in the switch when specifying listening multiaddresses containing ip6 component. Ensure ip6 addresses are advertised in identify. Implement measures to handle duplicated IPs in peerstore/addresses being listened to (i.e 192.0.2.42 vs 2001:db8::1234).
Deliverables
- Identify advertises correct /ip6 addrs; observed addrs tracked per transport
Testing, Interop & CI
- fully qualified name:
vac:p2p:ift:2025q4-nimlibp2p-ipv6:testing - owner:
- status: not started
- start-date:
- end-date:
Description
Ensure IPv6 support and ensure there are no regressions in IPv4 support. Add test units demonstrating the support, and check that interop against other implementations is achieved
Deliverables
- Test units focusing on IPv6
- Interop tests against other implementations that support IPv6
