Cant see the AWS public IP Adress

Question

I have problems understanding how the amazon's public ip list here works. For example, when I query IP 35.165.39.114, it shows that the IP is allocated to amazon:

NetRange:       35.152.0.0 - 35.183.255.255
CIDR:           35.152.0.0/13, 35.176.0.0/13, 35.160.0.0/12
But the IP list only has these:

{
  "ip_prefix": "34.248.0.0/13",
  "region": "eu-west-1",
  "service": "AMAZON"
},
{
  "ip_prefix": "35.153.0.0/16",
  "region": "us-east-1",
  "service": "AMAZON"
},

I can't see the IP Adress here, can anyone tell me the reason for it?

35.160.0.0/13 is a CIDR Range. 35.165.39.114 falls between the range.

Starting IP:   35.160.0.1           
Ending IP:   35.167.255.254     
Total No of IPs: 524286
