Why the traefik pod dns address are different with other pod dns in kubernetes

When I acsess the same domain in the same kuberetes, the traefik v2.10.1 pod dns are different with others, this is the traefik dns look like:

/ $ nslookup kubernetes.default
Server:		100.100.2.136
Address:	100.100.2.136:53

** server can't find kubernetes.default: NXDOMAIN

** server can't find kubernetes.default: NXDOMAIN

and this is the other pod dns look like:

root@y-websocket-service-9654986bc-cf65m:/home/node/app# nslookup kubernetes.default
Server:         10.96.0.10
Address:        10.96.0.10#53

Name:   kubernetes.default.svc.cluster.local
Address: 10.96.0.1

this is the traefik define in kubernetes look like:
