Por que o endereço DNS do pod traefik é diferente de outros DNS do pod no Kubernetes

Quando eu acesso o mesmo domínio nos mesmos kuberetes, os v2.10.1dns do traefik pod são diferentes dos outros, este é o dns do traefik:

/ $ 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

e este é o outro pod DNS parecido com:

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

esta é a definição do traefik no kubernetes v1.29.x, semelhante a:
