What is the difference between DHCP and DHCPv6?
What is the difference between DHCP and DHCPv6?
The differences are that DHCPv6 uses Unique Identifiers, while DHCP uses MAC addresses to identify the client. DHCP messages are transmitted over IPv4 packets and DHCPv6 is transmitted over IPv6 packets. DHCPv6 uses Router Advertisement (RA) and IPv6 multicast messages and DHCP uses broadcast IPv4 messages on the LAN.
Which is better DHCPv6 or Slaac?
If you do not have any requirement to restrict the hosts that can attach to the network using IPv6, then SLAAC, combined with DNS advertisement in the RA, and possibly with DDNS (if needed), would be the right choice. However, if the environment must be more secure, then DHCPv6 is likely to be the better solution.
When should I use DHCPv6?
DHCPv6 provides more control to the administrator in assigning addresses. If you really want that sort of control over your IPv6 addresses, you don’t understand IPv6 yet. It also can be used to provide additional configuration parameters beyond the basic address/gateway supported through autoconfiguration.
Is DHCPv6 necessary?
1) For address provisioning DHCPv6 is no longer needed (hosts can do that on their own, via SLAAC), for the default gateway it can’t be used, and the vast majority of systems can get their DNS resolvers via RAs (option 25/RDNSS as of RFC 8106; see also Chris’ post when Windows 10 eventually had it).
Should I disable IPv6 DHCP?
We do not recommend that you disable IPv6 or its components. If you do, some Windows components may not function. We recommend using Prefer IPv4 over IPv6 in prefix policies instead of disabling IPV6.
What are the new features of DHCPv6?
9. IPv6 Features
- New Header Format.
- Larger Address Space.
- Efficient and Hierarchical Addressing and Routing Infrastructure.
- Stateless and Stateful Address Configuration.
- Built-in Security.
- Better Support for QoS.
- New Protocol for Neighboring Node Interaction.
- Extensibility.
Why is it beneficial to use stateless DHCPv6?
The stateless Dynamic Host Configuration Protocol for IPv6 (DHCPv6) feature allows DHCPv6 to be used for configuring a node with parameters that do not require a server to maintain any dynamic state for the node.
What is the purpose of Slaac and DHCPv6 what are their differences?
SLAAC automatically works with a router, while Stateless DHCPv6 gives addresses using SLAAC and extra information using DHCP. The only configuration where the server gives IPv6 addresses is the Stateful one.
Should I enable IPv6 on my router 2021?
Likewise, disabling IPv6 can cause certain problems, especially if your router is already using an IPv6 address. However, you should keep IPv6 enabled even if you use an IPv4 network or install a VPN that supports IPv6, like NordVPN. Otherwise, some Windows features (like Quick Assist) might not work properly.
Does IPv6 slow down internet?
If you have IPV6 turned on, DNS lookups are 2 to 3 times slower than with IPV4. That’s why it seems as if your computer has “trouble connecting” to web sites. When you initiate a connection to any site, the first thing it does is look up the IP address in DNS. DNS lookups are slow on IPV6 for several reasons.
Is IPv6 address assignment easier using DHCPv6?
An advantage of DHCPv6 for dynamic address assignment is that it is capable of providing additional information to the nodes. DHCPv6 provides DNS information and uses a 16-bit option space.
What are the advantages of IPv6?
Key benefits to IPv6 include:
- No more NAT (Network Address Translation)
- Auto-configuration.
- No more private address collisions.
- Better multicast routing.
- Simpler header format.
- Simplified, more efficient routing.
- True quality of service (QoS), also called “flow labeling”
- Built-in authentication and privacy support.
