Sep 03, 2013 · IPv6 isn’t like IPv4. That fe80 field at the start means the same thing to a network administrator. Hexadecimal is confusing. The IPv6 address show by that ip addr command is fe80::2000:aff:fea7
Aug 09, 2017 · If you assign the link-local address FE80::1 on each of its interfaces and if that link-local address is unique on each of those LAN segments, then this becomes the default gateway for the hosts on those LANs. Therefore, each host, no matter on which LAN, will see FE80::1 as the next-hop IPv6 address for the default route in its routing table. Jun 15, 2020 · Hello John, 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. The design philosophy behind IPv6 is that having a reasonably-structured address space is more important than conserving addresses. Incidentally, IPv4 was conceived with the same idea (which is why each device has 16 million loopback addresses, but only ever uses the 127.0.0.1 address, and most of the class D and E addresses are unused). Sep 03, 2013 · IPv6 isn’t like IPv4. That fe80 field at the start means the same thing to a network administrator. Hexadecimal is confusing. The IPv6 address show by that ip addr command is fe80::2000:aff:fea7 IPv6 Lookup Tool. The IPv6 Info tool provides a complete set of IPv6 address information. The IPv6 Info tool provides WHOIS information, Autonomous System Number (ASN) information, expanded and compressed IP address information, and reverse lookup information for an IPv6 address. Free IP address tool translate IPv6 address from dotted-decimal address to decimal format and vice-versa.
Mar 05, 2019 · IPv6 address with % sign is called Link-Local IPv6 address. IPv6 addressing is done n this way. An address exists on every computer NIC that has network part same for all computers in the world. That part is called network identifier and is written fe80:0000:0000:0000 or to be short fe80::
Figure 2: The IPv6 link-local address, better illustration. The better illustration of an IPv6 link-local address is: Examples: fe80::1/10, fe80:1::1/32 and fe80::1:1/64 are all IPv6 link-local addresses; their prefix lengths are 10, 32 and 64 respectively. Each such IPv6 address has the leftmost 10 bits equal to binary 1111111010.

Oct 25, 2018 · No subnet6 declaration for eth0 (fe80::20c:29ff:fe1a:cc12). ** Ignoring requests on eth0. If this is not what you want, please write a subnet6 declaration in your dhcpd.conf file for the network segment to which interface eth0 is attached. ** This problem is mostly ISC DHCP-specific; Kea solves the problem differently. Mar 05, 2019 · IPv6 address with % sign is called Link-Local IPv6 address. IPv6 addressing is done n this way. An address exists on every computer NIC that has network part same for all computers in the world. That part is called network identifier and is written fe80:0000:0000:0000 or to be short fe80:: Address prefix is always FE80::/64 and IPv6 router never forwards link-local traffic beyond the link. These addresses are comparable to the auto-configuration addresses 169.254.0.0/16 of IPv4. A link-local address is also required for Neighbor Discovery processes. JUNOS also allows You to configure link local addresses with masks shorter than 64: ## Using /48 netmask [edit interfaces ge-0/0/1] regress@R1# set unit 0 family inet6 address fe80::1111:2222:3333:4444/48 [edit interfaces ge-0/0/1] regress@R1# show unit 0 { family inet { address 10.0.113.2/24; address 203.0.113.6/29; } family inet6 { address fe80::1111:2222:3333:4444/48; } } [edit interfaces
