[Fixed] “Local Area Connection” doesn’t have a valid IP configuration

The standard prescribes that address collisions must be handled gracefully. In IPv6, the block fe The most common use of private addresses is in residential IPv4 networks, since most Internet service providers ISPs allocate only a single publicly routable IPv4 address to each residential customer, but many homes have more than one computer or other Internet connected device, such as smartphones.

Private addresses are also commonly used in corporate networks , which for security reasons, are not connected directly to the Internet.

Often a proxy, SOCKS gateway, or similar devices are used to provide restricted Internet access to network-internal users. In both cases, private addresses are often seen as enhancing network security for the internal network, since it is difficult for an Internet external host to connect directly to an internal system.

It is common for packets originating in private address spaces to be misrouted onto the Internet. Private networks often do not properly configure DNS services for addresses used internally and attempt reverse DNS lookups for these addresses, causing extra traffic to the Internet root nameservers. The AS project attempted to mitigate this load by providing special blackhole anycast nameservers for private address ranges which only return negative result codes not found for these queries.

Organizational edge routers are usually configured to drop ingress IP traffic for these networks, which can occur either by misconfiguration, or from malicious traffic using a spoofed source address. Less commonly, ISP edge routers drop such egress traffic from customers, which reduces the impact to the Internet of such misconfigured or malicious hosts on the customer's network. Since the private IPv4 address space is relatively small, many private IPv4 networks unavoidably use the same address ranges and hence the same addresses.

This can create a problem when merging such networks, as multiple devices are likely to have the same address. In this case, networks or hosts must be renumbered, often a time-consuming task, or a network address translator must be placed between the networks to translate or masquerade the duplicate addresses. For IPv6, RFC defines unique local addresses , providing an extremely large private address space from which each organisation can randomly or pseudo-randomly allocate its own bit prefix, each of which allows organisational subnets.

With space for about one trillion 10 12 prefixes, it is extremely unlikely that two network prefixes in use by different organisations are the same, provided each of them was allocated randomly, as specified in the standard.

When two such private IPv6 networks are connected or merged, the risk of an address conflict is therefore virtually absent. Modify the value of your network connection Method 2: Reinstall your network adapter software Method 3: Change network adapter settings Method 1: Reinstall your network adapter software The error can be also caused by your outdated or corrupted network adapter driver. After installing the new driver, please restart your PC to make it take effect.

Hope we do help you fix the error. Got this up and running but the xbox had strict NAT. Decided to go back to the original setup for now but it won't connect In the sharing centre I have unidentified network, no internet access alongside my 1. Then if I skip to the next step I get "Local area connection does not have valid IP configuration" I've spent hours on google, tried static IP address, updating and rolling back network adapter drivers etc etc.

Don't want to have to go back to XP This thread is locked. You can follow the question or vote as helpful, but you cannot reply to this thread. I have the same question
