For some reason I need get srv records in kube-dns , below is what I got

[root@devo-ui-37mmn /]# nslookup
> set q=srv
> devo-ui.dev.svc.cluster.local.
Server:     10.254.0.2
Address:    10.254.0.2#53

devo-ui.dev.svc.cluster.local   service = 10 100 0 3339386563373339.devo-ui.dev.svc.cluster.local.
> 

host devo-ui-37mmn is one of my pod, the query string devo-ui.dev.svc.cluster.local is the service in kubernetes and devo-ui-37mmn is connect to the service.

So I think the record 3339386563373339.devo-ui.dev.svc.cluster.local. is the same pod, but what is the meaning of digital data "3339386563373339" and how to convert the number to human readable data, thank you.
