Is it safe to pass your ip to communicate with ftp?

Question

PHP

The situation is this: the hosting support service writes to me that in order for me to work with the site directory via ftp, I need to give them my IP, and then they will bind it and I will have access to ftp in the browser. Is it safe to share your IP at all?

Answer 1

It's not entirely clear how it works

# Исходный словарь
>>> prefs = {'person1': {'item1': 5, 'item3': 10},
             'person2': {'item1': 3, 'item2': 6}}
# Обращение к значению ключа вложенного словаря
>>> prefs['person1']['item1']
5
# Разница значений ключей
>>> prefs['person1']['item1'] - prefs['person2']['item1']
2
# Функция pow() возведения числа в степень 
>>> pow(5, 2)
25
>>> pow(5, 2) == 5 ** 2
True
# Перебираем ключи словаря
>>> [key for key in prefs['person1']]
['item1', 'item3']
>>> [key for key in prefs['person2']]
['item1', 'item2']
# Находим общие для словарей prefs['person1'] и prefs['person2'] ключи
>>> [key for key in prefs['person1'] if key in prefs['person2']]
['item1']
# Функция sum() нахождения суммы
>>> x = list(range(5))
>>> x
[0, 1, 2, 3, 4]
>>> sum(x)
10

Answer 2

It is safe, only all normal hostings have a control panel where you assign IPs yourself, add new ones, and inside the virtual machine you yourself raise the necessary services.

Answer 3

And you have no choice. And secondly, if it changes, it will be even more fun.

Answer 4

Absolutely safe.
But if you access the Internet from under NAT, then you need to transfer the IP address of the NAT server.
