Spectrum has historically delegated a /56. It seems like I’m getting a /64 now regardless of what I specify in my dhcpcd settings. Has that changed for anyone else? The problem manifested itself over the last few weeks as intermittent DNS failures. I use Cloudflare’s IPv6 servers exclusively for DoT but also as a canary for when IPv6 breaks.
17.08.2019 · The “IPv6 Interface” to track should be set to WAN unless perhaps you have more than one WAN interface/gateway. For the “IPv6 Prefix ID”, you may enter anything from 0 to F (hexadecimal) since we have 4 bytes to allocate to our local networks (up to 16 networks).
dhcpv6-pd { pd 0 { interface eth1 { host-address ::1 prefix-id :0 service slaac } ... Comcast, Spectrum, everyone seem to have generic advice and not the ...
The easiest way to allow a device to communicate over either IPv4 or IPv6 is to assign to it both an IPv4 address and an IPv6 address. This is called dual stacking. The device can then "speak" either protocol, depending upon either the type of address DNS gives it for a destination or the type of protocol used by another device sending it packets to which it must respond.
19.03.2020 · @caskater4 said in IPv6 on SoCal Spectrum: I don't see anything that would tell me the prefix size. The subnet mask on the router is 128. As I mentioned earlier, if you look at the text below the prefix ID box on the LAN page, it may say. For example, mine says the available range is 0-ff, which is correct for my /56.
Hello, Yesterday, i received an ARRIS SBG6950AC2 modem/router that was purchased from Amazon. Spectrum support was able to activate the modem/router without a problem. The cable/internet are working properly, but noticed that IPv6 internet protocol was not working. Ran an IPv6 test on the internet and came back that we did not have connectivity, only IPv4 on all …
IPv4 addresses have a subnet mask but instead of typing something like 255.255.255.0 we use a prefix length for IPv6. Here is an example of an IPv6 prefix: 2001:1111:2222:3333::/64. This is pretty much the same as using 192.168.1.1 /24.
07.08.2021 · IPv6 Prefix Delegation on Spectrum with dhclient. A few years ago, Spectrum (a US cable company formed from the combination of Charter and Time Warner Cable) started offering IPv6 Prefix Delegation (PD) /64s. The device connected to the cable modem will normally get an individual global dynamic IPv6 address via Router Advertisement, but Prefix ...
21.10.2021 · IPv6 Prefix ID. If the ISP has delegated more than one prefix via DHCPv6, the IPv6 Prefix ID controls which of the delegated /64 subnets will be used on this interface. This value is specified in hexadecimal. For example, If a /60 delegation is supplied by the ISP that means 16 /64 networks are available, so prefix IDs from 0 through f may be used.
Charter Spectrum provides IPv6 support. It's working on my network, and all my devices have v6 addresses that can access the internet. Great. My router is a Synology RT-2600ac, which works but is not the most configurable or understandable thing when it comes to v6. Spectrum only works with the RT2600ac when I set up Prefix Delegation with DHCPv6.
05.07.2019 · Arris modem from Spectrum DOES give proper IPV6 via DHCPv6 to its direct clients. My pfSense on the WAN interface, when set up with either “None” or “/56” as IPV6 prefix DOES get IPV6 address from the modem. Following various guides, it should be as simple as setting my LAN interface on pfSense to “track” the WAN interface, but to ...
