Keep specific hostname when adding domain-based network alert

[achillean]

If a user runs a command such as:

shodan alert domain www.shodan.io

Then the CLI will create a domain-based network alert for shodan.io. However, it should create a network alert for just www.shodan.io which is how the Shodan Monitor website operates.

@achillean Is this issue still something that you would like to be added to the Shodan CLI?

Yes, but we probably need to add something like tldextract as a dependency to identify whether the user is setting up a specific hostname. The workflow would look something like:

1. Parse the domain with tldextract
2. Check if the provided domain has a subdomain
3. If it has a subdomain then lookup the IPv4 and IPv6 addresses for the hostname and use that for the list of IPs. If it doesn't have a subdomain then grab the list of IPs from DNSDB; i.e. what we're currently doing.
4. Create the new asset group with the list of IPs

Understood! I'll work on this!
