Transport_address showing issue

Elastic Stack Elasticsearch
1

when I execute _nodes/stats for my cluster, all nodes shows:
"transport_address": "inet[/XXX.XXX.XXX.XXX:9302]",
but there is one shows different:
"transport_address": "inet[XXX.XXX.XXX.XXX/XXX.XXX.XXX.XXX:9302]",

why does this happen?

most nodes show: inet[/ipaddress:port]
but the only one show: inet[/ipaddress/ipaddress:port]
it's really wired. can anyone help to answer this?

is this a minor bug of ES? if so, I'd like to open it in github
