نبذة مختصرة : Proxyservers can be used to connect the user to the Internet, which provides different levels of functionality, security, and privacy,and can be configured as web filters or firewalls that protect the computer from Internet threats Under the health of proxyaddresses, we mean the ability to send requests to various resources or services and receive responses. If the request was sentand no response was received, it can be concluded that the proxy address is not working. If a response is received, it can beconcluded that the proxy address is operational. Factors that can influence, sending a request and receiving a response froma resource are considered. An analysis of the considered factors showed that it is impossible to unambiguously conclude theperformance of a proxy address if we take into account only the fact of the presence or absence of a response from the resource.The conditions for confirming or refuting the performance of a proxy address are identified, which are taken as input data ofthe model proposed for assessing the performance of a proxy address. As a model, a neural network in the form of a threelayerperceptron was used, the training of which is performed by the method of error backpropagation. The created modelwas tested to determine the health status of proxy addresses using test datasets. Based on the results of research and experiments,an application was created that searches the Internet for resources with proxy addresses and checks their performance. ; Для підключення користувача до Інтернету можна використовувати proxy-сервери, які забезпечують різнірівні функціональності, безпеки та конфіденційності, і які можна налаштувати як веб-фільтри або брандмауери,що захищають комп’ютер від інтернет-загроз. Під працездатністю proxy-адресів мається на увазі можливість від-правляти запити на різні ресурси або сервіси та отримувати відповіді. Якщо запит був відправлений, а відповідь такі не отримана, можна зробити висновок, що proxy-адреса не працездатна. У випадку отримання відповіді можназробити ...
