I am trying to write a script that will take a FQDN and give me the hostname as well as the (sub)domain.
I am able to get the hostname, but I can't figure out how to also get the entire domain, including any subdomains.
Please note that these domains & subdomains would be internal domains and not public domains.
import re
words = "testing.something.thisdomain.com"
stuff = re.match(r"(.+?)(?=\.)", words)
print(stuff.group(1))
This works even if your fqdn does not have any subdomains
Code:
fqdn = "testing.something.thisdomain.com"
tld, domain, *sub_domains = fqdn.split(".")[::-1]
print(tld,domain,sub_domains)
Output:
com thisdomain ['something', 'testing']
Instead of doing a bunch of fancy regex couldn't we just use split on the string and print which part you need?
words = "testing.something.thisdomain.com"
stuff = words.split(".")
print(stuff[1])
