[punycode](https://en.wikipedia.org/wiki/Punycode) (see
[this article](https://www.xudongz.com/blog/2017/idn-phishing/) for a good description of why this is important):

```
!!! warning "Underscores in Hostnames"
In Pydantic, underscores are allowed in all parts of a domain except the TLD.
Technically this might be wrong - in theory the hostname cannot have underscores, but subdomains can.
To explain this; consider the following two cases:
- `exam_ple.co.uk`: the hostname is `exam_ple`, which should not be allowed since it contains an underscore.
- `foo_bar.example.com` the hostname is `example`, which should be allowed since the underscore is in the subdomain.
Without having an exhaustive list of TLDs, it would be impossible to differentiate between these two. Therefore
underscores are allowed, but you can always do further validation in a validator if desired.
Also, Chrome, Firefox, and Safari all currently accept `http://exam_ple.com` as a URL, so we're in good
(or at least big) company.

The `NameEmail` has two properties: `name` and `email`.
In case the `name` is not provided, it's inferred from the email address.
```python
from pydantic import BaseModel, NameEmail
class User(BaseModel):
email: NameEmail
user = User(email='Fred Bloggs <fred.bloggs@example.com>')

print(user.email.name)
#> Fred Bloggs
user = User(email='fred.bloggs@example.com')
print(user.email)
#> fred.bloggs <fred.bloggs@example.com>
