What’s better RADVD or DHCPv6 for local network with IPv6


today I got a new router and now I want to enable IPv6 on my network. But the thing is I don't know what the better option is since TP-Link gives me two ways to get IPv6 on my network.

The first option is RADVD and second option is DHCPv6. Now my question is which is the best solution? And if RADVD is better, should I enable RDNSS and ULA?

Thanks in advance.

  • You need at least radvd. Router advertisements communicate to devices on the network what the default gateway is and what the network configuration is. You always need that.

    The router advertisement can tell clients whether they are allowed to choose their own addresses or not (auto configuration). If you allow this then you might not need DHCP at all.

    Then you can add DHCP, either stateless or stateful. Stateless DHCP tells clients configuration options like DNS resolvers etc without providing addresses (useful if you allow auto configuring). Stateful DHCP also provides addresses.

    As you need radvd anyway it's the easiest, possibly combined with stateless DHCP. Don't bother with stateful DHCP unless you really need to manage addresses manually.
