Why is my default gateway FE80?
What this means is that you have a public IP address through DHCP. This is directly from the network of your internet service provider and not from your router. In such a scenario, users are often not able to swap their devices.
What is a 2001 IPv6 address?
The prefix 2001:db8::/32 is a special IPv6 prefix that is used specifically for documentation examples. You can also specify a subnet prefix, which defines the internal topology of the network to a router. The example IPv6 address has the following subnet prefix. The subnet prefix always contains 64 bits.
Why are there 2 link-local IPv6 addresses?
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. The system will keep the old address for as long as necessary.
Is FE80 link-local?
A link-local address is an IPv6 unicast address that can be automatically configured on any interface using the link-local prefix FE80::/10 (1111 1110 10) and the interface identifier in the modified EUI-64 format. Link-local addresses are not necessarily bound to the MAC address (configured in a EUI-64 format).
Does IPv6 need gateway?
As more companies move away from IPv4 capabilities and toward using IPv6, it is critical to have a flexible, secure, adaptable gateway. The gateway address will be designated noting how traffic can be routed and managed. The IPv6 gateway works like the IPv4 gateway, but is faster and far more secure.
What IP address starts with 2001?
An example of an IPv6 address is: 2001:0db8:85a3:0000:0000:8a2e:0370:7334.
Why does my IPv6 have 3 addresses?
Having 3 IP addresses means that your system can be communicated with using three different IP addresses, and most likely means you have WiFi turned on and an Ethernet cable plugged in. One will be the loop back address (127.0. 0.1) and that is only useful on the system itself.
How many IPv6 addresses should my WiFi have?
IPv6 addresses are assigned to organizations in much larger blocks as compared to IPv4 address assignments—the recommended allocation is a /48 block which contains 280 addresses, being 248 or about 2.8×1014 times larger than the entire IPv4 address space of 232 addresses and about 7.2×1016 times larger than the /8 …
What does the fe80 : / 10 range mean?
Addresses in the fe80::/10 range are link-local addresses. The addresses are only significant to the link on which they reside, so a device with multiple interfaces may have the same address, and certainly will have the same link-local network, on all its interfaces. That’s where the % sign comes into play.
What does fe80 1% lo0 mean in OS X?
We are considering the record “fe80::1%lo0 localhost” in the file /etc/hosts/ in OS X. It means for the hostname “localhost” use IPv6 link-local address “fe80::1” in zone “lo0”. Link-local means that this address is not routable and will be discarded by any router in the local network (at least they should).
What are the fe80 : / 10 addresses really for?
05-26-2009 12:07 PM 05-26-2009 12:07 PM the FE80::/10 are the link local addresses. It is correct that you don’t see them in the routing table: as explained in a previous thread actually it is a single IPv6 /64 subnet using eui-64 format what you get.
What does the fe80 field at the start of IPv6 mean?
That fe80 field at the start means the same thing to a network administrator. The IPv6 address show by that ip addr command is fe80::2000:aff:fea7:f7c. That’s a translation, not the original address.
