In docs

Display one or many resources

Prints a table of the most important information about the specified resources. You can filter the list using a label selector and the --selector flag. If the desired resource type is namespaced you will only see results in your current namespace unless you pass --all-namespaces.

If you will check manual for kubectl get you will get information about -o flag.

-o, --output='': Output format. One of: json|yaml|wide|name|custom-columns=...|custom-columns-file=...|go-template=...|go-template-file=...|jsonpath=...|jsonpath-file=... See custom columns [], golang template [] and jsonpath template [].

Thats mean you can get output in YAMLs or JSON format. Detailed information can be found in this doc.

As @Bernard Halas mentioned, you can just use kubectl get nodes -o wide.

Another option is use describe with grep. -A will print number lines of trailing context. Its helpful if you need to get list about information per node.

$ kubectl describe node | grep Addresses: -A 4
  InternalDNS:  gke-test-default-pool-d11b1330-g44z.c.composite-rune-239911.internal
  Hostname:     gke-test-default-pool-d11b1330-g44z.c.composite-rune-239911.internal
  InternalDNS:  gke-test-default-pool-d11b1330-gtpj.c.composite-rune-239911.internal
  Hostname:     gke-test-default-pool-d11b1330-gtpj.c.composite-rune-239911.internal
  InternalDNS:  gke-test-default-pool-d11b1330-r4dw.c.composite-rune-239911.internal
  Hostname:     gke-test-default-pool-d11b1330-r4dw.c.composite-rune-239911.internal

You can also use YAML or JSON format. Output will be similar to previous one.

$ kubectl get nodes -o yaml | grep addresses: -A 8
    - address:
      type: InternalIP
    - address:
      type: ExternalIP
    - address: gke-test-default-pool-d11b1330-g44z.c.composite-rune-239911.internal
      type: InternalDNS
    - address: gke-test-default-pool-d11b1330-g44z.c.composite-rune-239911.internal
      type: Hostname

In addition if you will need some specific output (only information you need and ar not print as default) you can use custom columns. It's based on YAML format.

$ kubectl get pods -o,NS:.metadata.namespace,HostIP:.status.hostIP,PodIP:status.podIP,REQ_CPU:.spec.containers[].resources.requests.cpu
Name                          NS        HostIP        PodIP       REQ_CPU
