Re: Question on DHCPv6 address assignment
Infoblox uses the ISC DHCP code. I'm thin on details. 1) What's the pattern with which addresses are generated/assigned? Are they sequential (fc00::1, fc00::2, etc.)? Random? Something else? The manual says When the server grants IPv6 leases, it uses an algorithm based on the DUID of the client. 2) What about their stability? Is there any intent/mechanism for them to be as stable as possible? Or is it usual for hosts to get a new address for each lease? I've observed a system obtaining different IPv6 addresses when presenting the same DUID. However, my impression is that hosts usually retain the same address across time. mark
Re: Question about IPAM tools for v6
Can anyone say whether existing IP Address Management tools that support IPv6 have built-in assumptions or dependencies on the /64 subnet prefix length, or whether they simply don't care about subnet size? We use Infoblox's IPAM. There aren't any limitations of which I'm aware in terms of allocating space and IPv6 prefix length in the IPAM. However, I don't know if there are restrictions when it comes to DHCPv6, as we've only set up /64s. mark
Re: Monitoring IPv6-MAC mappings
We use netdisco www.netdisco.org. It's an enterprise tool for mapping IP-MAC and MAC-switchport. It uses SNMP to snoop router ARP/ND caches and switch forwarding tables. A royal pain to install, but very useful. It has a postgres backend and privacy addresses might make for serious trouble there (we're running DHCPv6).
