Can an interface have multiple IPv6 addresses?
IPv6 is designed so that multiple addresses must exist on any interface and the application may not necessarily know which IP address is relevant. IPv6 addresses have scope (link-local, site-local and global) and may have all three addreses and multiple global IPv6 addresses.
What are the two rules for compressing an IPv6 address?
Rule 1: When there are continuous zeros (0s) in the IPv6 address notation, they are replaced with ::. This rule is also known as zero compression. Rule 2: Leading zeros (0s) in the 16 bits field can be removed.
Why do I get multiple IPv6 addresses?
A device generates new 64 bits every once in a while and uses that in the IPv6 address. Because new addresses are generated regularly the addresses are marked as temporary . A device can have multiple privacy extension addresses if the system is still using an old address when a new address is being generated.
How do I expand my IPv6 address?
To expand the compressed IPv6 address, perform the following steps.
- Open the IPv6 Expander Tool.
- Enter a compressed IPv6 address. Suppose you enter that IPv6 address 1050::5:600:300c:326b.
- After providing, click on the “Expand IPv6” button.
- The tool processes your request and gives you the following results.
What is the prefix of the IPv6 interface?
This prefix is the subnet prefix of the interface IPv6 primary static address. This option will help all hosts in the network to auto-configure an IPv6 address based on the subnet prefix.
How does a host configure an IPv6 address?
Hosts configure IPv6 addresses based on Router Advertisements (RA). If the RA has the prefix information, hosts combine the prefix and a unique Interface Identifier address to derive an IPv6 address. M = 1, O = 1: IPv6 hosts use DHCPv6 for both IPv6 address and other network parameter settings.
How to disable all IPv6 traffic on the interface?
Disable all IPv6 Traffic on the Interface: Improves firewall performance for non-IPv6 traffic if the firewall is deployed in a pure IPv4 environment. Enable Listening to Router Advertisement: Checking this option would force SonicWall to receive router advertisement.
Do you need a globally unique IPv6 address?
The nodes do not need a globally unique address to communicate. Routers will not forward datagram using link-local addresses. IPv6 routers must not forward packets that have link-local source or destination addresses to other links.
