I did a test to create index:

# Add Index

PUT /access.log.2020.04.07/\_doc/1  
{  
"domain":"[www.amazon.com](http://www.amazon.com)",  
"status":200  
}

#There is no problem when I query this index, GET \_cat/indices  
yellow open access.log.2020.04.07 t\_IYm\_OFQqmx83ObV4Bodw 5 1 1 0 4.5kb 4.5kb

But If my index name contains IP：  
PUT /access.log.192.168.10.7/\_doc/1  
{  
"domain":"[www.amazon.com](http://www.amazon.com)",  
"status":200  
}  
#GET \_cat/indices  
yellow open access.log.x.x.x.x r3Iut699QPqO4awkTwpn4g 5 1 1 0 6.9kb 6.9kb

Why does the index name become x.x.x.x?

But the index name displayed in kibana is normal

Has anyone encountered this situation? I tested it with ES 6.X and 7.X version,All have this kind of problem

Welcome to our community! 😃

I just tried this on 7.11.1;

```auto
PUT /access.log.192.168.10.7/_doc/1
{
"domain":"www.amazon.com",
"status":200
}

```

Response;

```auto
{
  "_index" : "access.log.192.168.10.7",
  "_type" : "_doc",
  "_id" : "1",
  "_version" : 1,
  "result" : "created",
  "_shards" : {
    "total" : 2,
    "successful" : 1,
    "failed" : 0
  },
  "_seq_no" : 0,
  "_primary_term" : 1
}

```

```auto
GET _cat/indices/access.log.*?v

```

Response;

```auto
health status index uuid pri rep docs.count docs.deleted store.size pri.store.size
yellow open access.log.192.168.10.7 8RO3hpV_QXaRBcFw3cqqpw 1 1 1 0 4kb 4kb

```

What is the response when you post your second `PUT`?
