Am I using Stateful or Stateless method for my dhcp router?

[Mirul]

Hello all.

Some of my friends telling me that I am using stateless method for my Dhcp router and some of them telling me that I am using stateful method. 

I attached the packet tracer for references.

This is the current configuration:

Any idea?

 - Depends what you mean by those terms, if you for instance incorporate that the DHCP service has to keep record of allocated addresses , then according to my opinion it becomes stateful.

Hi @Mirul ,

In your case you are using statefull, because when using DHCP, the router keeps a record of the addresses provided by DHCP.

When a PC obtains addressing by itself based on the parameters of the router, then the router does not keep any record (stateless).

Hey,

This shows up when I type in router#show ipv6 int *any interface*

Host using stateless autoconfig for addresses.

I'm really confused right now.

Hi @Mirul ,

I have reviewed and effectively, the DHCP that can be configured in PT is a stateless.
The stateful DHCP cannot be configured in PT, it seems.
I leave you this stateful DHCP guide, but in PT not all commands are accepted:
