What is IPv6 lease time?
Select the Scavenge free, expired and released leases after check box and specify the number of hours, days, or weeks that free, expired, and released IPv6 leases remain in the database before they are automatically deleted. The minimum is 6 hours and the maximum is 180 days. The default is one week.
Does IPv6 support Slaac?
Support for IPv6 SLAAC Privacy Extensions All versions of Mac OS X from 10.7 onward. All versions of iOS since iOS 4.3. All versions of Android since 4.0 (ICS)
Which is better Slaac or DHCPv6?
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.
What is a Slaac IPv6 address?
SLAAC stands for Stateless Address Autoconfiguration and the name pretty much explains what it does. It is a mechanism that enables each host on the network to auto-configure a unique IPv6 address without any device keeping track of which address is assigned to which node.
How long is DHCP lease time?
24 hours
The standard DHCP lease time is 24 hours, but you can change it to meet your network’s needs. For example, if you’re setting up a lease time on your restaurant’s WiFi network, you can restrict it to an hour or two while a guest office network could have about 12 hours.
What is ipv4 lease time?
Generally, the recommended time to lease an IP address is 48 hours (172800 seconds) to renew the IP address once a day. After applying the specified parameters, clients will receive an IP address for 1 minute, after which they will send a request to the DHCP server for a new IP address every 30 seconds.
Does Slaac use EUI 64?
Stateless autoconfiguration or SLAAC SLAAC is a method in which the host or router interface is assigned a 64-bit prefix, and then the last 64 bits of its address are derived by the host or router with help of EUI-64 process which is described in next few lines. SLAAC uses NDP protocol to work.
What protocols does Slaac use?
SLAAC uses NDP protocol to work and NDP is another thing that I have written about.
Why is DHCPv6 useful?
If you’re running a dual-stack environment, with both IPv4 and IPv6, then it probably makes sense to use DHCP and DHCPv6. This gives you the most consistency and control over your environment.
Is DHCPv6 necessary?
It is the IPv6 equivalent of the Dynamic Host Configuration Protocol for IPv4. DHCPv6 is not necessary for configuring hosts with the addresses of Domain Name System (DNS) servers, because they can be configured using Neighbor Discovery Protocol, which is also the mechanism for stateless autoconfiguration.
What is the purpose of Slaac?
(StateLess Address Auto Configuration) The preferred method of assigning IP addresses in an IPv6 network. SLAAC devices send the router a request for the network prefix, and the device uses the prefix and its own MAC address to create an IP address.
How do you set up Slaac?
The basic configuration of SLAAC on a Cisco device is quite simple….Table 1: Basic IPv6 SLAAC Configuration.
| 1 | Enter privileged EXEC mode | Router>enable |
|---|---|---|
| 5 | Configure an IPv6 address | Router(config-if)#ipv6 address ipv6-address/prefix-length |
| 6 | Enable the interface | Router(config-if)#no shutdown |
How is SLAAC implemented on IPv6?
SLAAC is implemented on the IPv6 client by listening for these local RA’s and then taking the prefix that is advertised to form a unique address that can be used on the network. For this to work, the prefix that is advertised must advertise a prefix length of 64 bits (i.e., /64); SLAAC will then dynamically form a host identifier that is 64
What is IPv6 tutorial?
IPv6 Tutorial. Internet Protocol version 6 (IPv6) is the latest revision of the Internet Protocol (IP) and the first version of the protocol to be widely deployed. IPv6 was developed by the Internet Engineering Task Force (IETF) to deal with the long-anticipated problem of IPv4 address exhaustion.
What is IPv6 leak protection and how does it work?
To ensure that you keep on receiving complete online anonymity, PureVPN offers IPv6 leak protection which is built to safeguard your online traffic from the eyes of hackers, trackers, and any other spying entity. Most VPNs suffer from IPv6 leak issues that expose the actual online identity of the person using the VPN.
What is the IPv6 loopback address for loopback?
In IPv6, the IPv6 address reserved for loopback use is 0000:0000:0000:0000:0000:0000:0000:0001/128. This loopback address is so lengthy and can be further simplified as ::1/128. This loopback address is so lengthy and can be further simplified as ::1/128.
