Hi,

Thanks for the response , but my question is

can router itself act as a dns server?

Yes, it is very much possible to configure router to act as DNS server. you need to define a static host name-to-address mapping in the host name cache of router.

check below URL to get more information.

Yes, but most of the following commands are not documented at all and it supports UDP/53 only (TCP/53 and zone transfer is not supported):

ip dns server

ip dns primary domain.com soa [refresh] [retry] [expire] [minimum]

ip host

ip host ns

ip host mx

ip host srv

show hosts

show ip dns primary

show ip dns statistics

The server will answer A and PTR quries.
