    Need help identifying a subnet

    Hello guys, I'd like to ask you a question.
    How can you determine something about the server just from seeing the subnet?
    Etc.: 94.249.100.93/32
    How many IP adresses can this subnet have ?
    What else can you tell about it ?
    Any help appreciated,
    V

    Hi,


    • The /32 give 30 hosts + 1 bcast + 1 net base; basically 30 usable IP addresses in this subnet.
    • It is an IPV4 address
    • Using nslookup reverse dns finds: 4.249.100.93 is from Jordan(JO) in region Middle East
    • The subnet belongs to go.com.jo
    • Public DNS does not seem to be setup for this
    • The hops are : TraceRoute from Network-Tools.com to 94.249.100.93 [94.249.x.93.go.com.jo]
      Hop (ms) (ms) (ms) IP Address Host name

    Hello,
    I thought that /32 stands for subnet mask 255.255.255.255 and thus it can only hold 1 host and have only one IP - 94.249.100.93 itself.
    Are you sure there are 30 usable IP's ?

    /27 gives you 32 Ip address not /32./32 only gives you 1 IP address.You can check below sheet for the IP range :
    notation resulting subnet
    netmask shorthand number of addresses
    255.255.255.0 /24 [8-bit] 28 = 256 = 254 hosts + 1 bcast + 1 net base
    255.255.255.128 /25 [7-bit] 27 = 128 = 126 hosts + 1 bcast + 1 net base
    255.255.255.192 /26 [6-bit] 26 = 64 = 62 hosts + 1 bcast + 1 net base
    255.255.255.224 /27 [5-bit] 25 = 32 = 30 hosts + 1 bcast + 1 net base
    255.255.255.240 /28 [4-bit] 24 = 16 = 14 hosts + 1 bcast + 1 net base
    255.255.255.248 /29 [3-bit] 23 = 8 = 6 hosts + 1 bcast + 1 net base
    255.255.255.252 /30 [2-bit] 22 = 4 = 2 hosts + 1 bcast + 1 net base
    255.255.255.254 /31 [1-bit] 21 = - invalid (no possible hosts)
    255.255.255.255 /32 [0-bit] 20 = 1 a host route (odd duck case)
