All of client computer use static IP address. When we checked, there is an autoconfiguration IPv4 on client computer. This happens when the user restart their PC or turn on their PC. Does anybody ever experience this problem? Thank you.

The stateless autoconfiguration in IPv6 provides some of the most important IPv6 settings but it is not readily extensible and as an example, as you pointed out very correctly, the DNS server address cannot be currently assigned via Router Advertisement messages.Sun, 22 Mar 2026 16:29:00 GMThttps://community.cisco.com/t5/networking-knowledge-base/understanding-ipv6-eui-64-bit-address/ta-p/3116953Introduction Extended Unique Identifier (EUI), as per RFC2373, allows a host to assign iteslf a unique 64-Bit IP Version 6 interface identifier (EUI-64). This feature is a key benefit over IPv4 as it eliminates the need of manual configuration or DHCP as in the world of IPv4.

During the stateless autoconfiguration process, DAD verifies the uniqueness of new unicast IPv6 addresses before the addresses are assigned to interfaces. If the duplicate address is the link-local address of the interface, the processing of IPv6 packets is disabled on the interface.Mon, 30 Mar 2026 00:41:00 GMThttps://community.cisco.com/t5/switching/basic-dns-question/td-p/3312340Solved: I need some help with this question (below) please- I understand the answer is "b" and DNS can prevent browsing of webpages if configured incorrectly, but so can having the wrong default gateway.

With this configuration, the interface should only obtain its configuration using RAs and the stateless address autoconfiguration (SLAAC).Sun, 29 Mar 2026 02:59:00 GMThttps://community.cisco.com/t5/blogs-general/auto-configuracion-de-direcciones-ipv6-con-slaac-y-stateless/ba-p/4735953Auto configuracion de direcciones IPv6 Objetivos Comprender la auto configuración de direcciones IPv6 sin estado SLAAC (Stateless Address AutoConfiguration) Comprender la asignación de direcciones utilizando un SLAAC mas uin pool de DHCP sin estado (Stateless DHCPv6) Stateless address autoconfig...Thu, 02 Apr 2026 04:05:00 GMThttps://community.cisco.com/t5/networking-knowledge-base/ipv6-essentials-icmpv6-and-ndp/ta-p/5024137It offers various services, including: Address Resolution (AR), similar to ARP in IPv4.
