How to Capture the IP Address of a Host

How To


Summary

When configuring a firewall rule, Microsoft Conditional Access named location, proxy exception, or another security control that does not support FQDN entries, you may need to convert a hostname (e.g., m3.maas360.com) into its IP address.

IP Addresses change frequently. Use the below steps for both macOS and Window to covert a hostname.

Steps

Windows – Using nslookup
Using <m3.maas360.com> as an example

  1. Open Command Prompt
  2. Run the Lookup command:

    nslookup m3.maas360.com
     
  3. Identify the Address Field:

    Server: UnKnown
    Address: fe80:: 6c7e: 67ff: fe7b:a864
    Non-authoritative answer: 
    Name: e6732.dscksd.akamaiedge.net
    Addresses: 2600:1404:6400:108e:: 1a4c
    2600:1404:6400:1089:: 1а4c
    72.247.201.42
    Aliases: m3.maas360.com
    maas360.com. edgekey.net
     

  4. If multiple IPs were returned, you may need to allow all. Confirm you resolved against the correct DNS server. To resolve against an exact DNS server:

    nslookup m3.maas360.com 9.9.9.9

    Use the following command to force IPv4 only:

    nslookup -type=A m3.maas360.com 

 

macOS – Using host
Using <m3.maas360.com> as an example

  1. Open Terminal
  2. Run the Lookup command:

    host m3.maas360.com
     
  3. Identify the Address Field:

    m3.maas360.com is an alias for maas360.com.edgekey.net.
    maas360.com.edgekey.net is an alias for e6732.dscksd.akamaiedge.net.
    e6732.dscksd.akamaiedge.net has address 23.203.94.149
    e6732.dscksd.akamaiedge.net has IPv6 address 2600:1404:6400:108e::1a4c
    e6732.dscksd.akamaiedge.net has IPv6 address 2600:1404:6400:1089::1a4c
     

  4. If multiple IPs were returned, you may need to allow all. Confirm you resolved against the correct DNS server. To resolve against an exact DNS server:

    host m3.maas360.com 9.9.9.9

    Use the following command to force IPv4 only:

    host -t A m3.maas360.com
