+## DHCPv6 Essentials (Attacker View)
+
+- **UDP ports**: clients listen on `546`, servers/relays on `547`.
+- **Multicast**: clients send Solicit/Information-Request to `ff02::1:2` (All DHCPv6 Relay Agents and Servers).
+- **Client identity**: DHCPv6 uses a **DUID** (Client Identifier option) instead of MAC-only identity, so spoofing requires matching the DUID rather than just L2.
+- **Stateful mode**: uses **IA_NA** (addresses) and optionally **IA_PD** (prefix delegation).
+- **Stateless mode**: uses **Information-Request** to fetch only options (DNS, domain search list, etc.).
+- **High-value option**: **DNS Recursive Name Server** (option 23) is the usual target for DNS takeover in mixed IPv4/IPv6 networks.
+- **High-value option**: **Domain Search List** (option 24) can leak internal namespaces and steer short-name resolution.
+- **High-value option**: **Client FQDN** (if sent) can leak internal naming and is often used to build targeted relay rules.
+
+## Passive Recon from DHCPv6 Traffic
+
+Sniffing DHCPv6 gives you organization-specific context without sending packets:
+
+- Internal DNS servers (option 23) and search domains (option 24).
+- Hostnames/FQDNs when clients send the FQDN option.
+- DUID formats (LLT/LL/UUID/EN) that help correlate hosts across address changes.
+
+If you need the full IPv6 MITM chain (RA + DHCPv6 DNS takeover + relay), see [Pentesting IPv6](pentesting-ipv6.md).
+
+## Rogue DHCPv6 / DNS Takeover (Practical Tools)
+
+Common offensive pattern: stand up a rogue DHCPv6 server, respond to Solicit/Information-Request, and deliver **attacker-controlled DNS** (and optionally addresses/prefixes). Practical tooling:
+
+- **mitm6** (Windows-focused DNS takeover):
+
+```bash
+sudo mitm6 -i eth0 -d corp.local
+```
+
+- **pretender** (DHCPv6 DNS takeover + LNR spoofing):
+
+```bash
+pretender -i eth0 --dry
+pretender -i eth0
+```
+
+- **THC IPv6 fake DHCPv6 server** (`fake_dhcps6`):
+
+```bash
+fake_dhcps6 <iface> <prefix/prefixlen> <dns-server> [dhcp-server-ip [mac]]
+```
+
+## Reconfigure Message Abuse (When Auth Is Missing)
+
+The **Reconfigure** message is designed for servers to trigger a Renew/Information-Request on clients. RFC 8415 requires clients to **discard unauthenticated** Reconfigure messages, but in networks where DHCPv6 authentication is unused or mis-implemented, spoofed Reconfigure frames can be leveraged to **force fresh DHCPv6 exchanges**, giving a rogue server another chance to inject DNS/search-list options.
+
+## Relay Agent Options & Policy Abuse
+
+Many enterprise/ISP deployments use DHCPv6 relays and apply policy based on relay options:
+
+- **Interface-ID** and **Remote-ID** are commonly inserted by relays to identify the client’s attachment point.
+- If an attacker can spoof or tamper with **Relay-Forward** traffic, they can influence how the server classifies the client and which policies/options it applies (address pools, DNS servers, prefix delegation, etc.).
