Re: Rogers IPv6 Status

This /64 IPv6 prefix, will it be static or Dynamic ? I noticed, when i rebooted my modem 3,4 part changed (1:2:3:4/64). Is this normal ?

Re: Rogers IPv6 Status

I don't work for Rogers so take this with a grain of salt. 

 

I don't think the IPv6 prefix will change unless the MAC address of the device connecting to the network changes. In other words, unless you make a hardware change the prefix should stay constant. I don't think Rogers has a policy to assign static prefixes to residential clients though.

 

My prefix has not changed since IPv6 went active which was a few weeks ago.

 

There are no guarantees but unlike with IPv4 where there is a limited pool of addresses to assign, the IPv6 address pool, or in IPv6 speak "prefixes," that Rogers has availble means that they don't need to worry about running short so they don't have to juggle them like they did for IPv4.

 

If your prefix has changed it may be due to another reason other than anything Rogers may be doing on their end.

DHCPv6-PD uses something called "DHCP Unique Identifier" (DUID) which usually contains the MAC or link local address of the modem or router.  This won't change, unless you change the hardware.

Re: Rogers IPv6 Status

I am 100% sure i didnt change my router in the last 365 days. My modem was always in bridge mode. 

another question: why is there no WAN ip address listed in my router's WAN interface ? Is this normal ?

Hello Raji,

 

While we do use Dynamic DHCP, as far as I'm aware, the prefixes in IPv6 shouldn't change.

Re: Rogers IPv6 Status

I'm seeing intermittent packet loss on IPv6 only. Is this a known issue?

Re: Rogers IPv6 Status

Raji, is the prefix changing regularly? If it was I one time thing I wouldn't worry about it and chock it up to a one-time event.

 

As for the WAN IPv6 address, I don't have a Netgear router but the router I do have does show the WAN address. You may need to contact Netgear for an answer to that one or find a netgear user community to find out what the story is about that.

Here's a smokeping from the last 3 hours showing significant packet loss. This is to Google over IPv6 (2607:f8b0:400b:80b::200e):

"While we do use Dynamic DHCP, as far as I'm aware, the prefixes in IPv6 shouldn't change. "

 

In my experience, the IPv4 DHCP address rarely changed, but the host name never changed, unless the hardware was changed as it was based on the modem and firewall MAC addresses.  Does the same apply to the IPv6 host name?  I don't see anything like a MAC address within my current IPv6 host name.

@gw280 I haven't seen your graph yet as the mods haven't approved it, but, have a look at my post #73 on the following page:

Perhaps what you are seeing will make more sense after reading thru the post.
