Can I have two DHCP servers for IPv4/IPv6?

in flag

I have an IPv6 block, However the network is based on an IPv4 only router. I can't change that router for several reasons.

Can I have a DHCPv6 server with DHCPv4 server? Or do I have to disable DHCPv4 from the IPv4 router?

Yes, these are independent, and the DHCPv6 server should also respond to v6 requests only.

If you use server software that supports both, you may need to explicitly disable responses to v4 requests, and you may run into issues if your DHCP server also updates local DNS (e.g. because an update flushes all records and then only adds records for one address family).

Also, the DNS settings handed out by both servers should be consistent.

If you don't need any features beyond address assignment, stateless autoconfiguration through router advertisements may be sufficient for you.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
