NTP Time Application

Application Information

The following page provides details on domains, networks, IPs, hosting services, and content delivery networks used by NTP Time.

Description

The Network Time Protocol (NTP) project is used to synchronize the time of electronic devices worldwide. The service is managed via the Network Time Foundation.

Network Intelligence

The network data shown here is also available via the Netify Data Feed API. We provide network intelligence to help deliver better digital experiences to end users and businesses.

Domains

Primary Domains

Primary Domains are owned and managed by the application vendor.

Platform Domains are often provided by hosting providers, content delivery networks, SaaS platforms and other third parties. It is important to identify these domains for DNS filters and hostname blocklists.

Core Networks

Applications are sometimes deployed on partner networks, parent company networks, or regional hosting providers. The following is a sample of NTP Time IP addresses deployed on this type of network.

Network	PoP	Category	Location	IP
Chunghwa Telecom	Core Network	ISP/Telco	Taiwan	36.234.250.164
EBOX	Core Network	ISP/Telco	Canada	74.116.186.120
Cox	Core Network	ISP/Telco	United States	98.186.143.148
VNPT	Core Network	ISP/Telco	Vietnam	103.179.189.201
Xfinity	Core Network	ISP/Telco	United States	107.3.86.105
and 449 more

Other Networks

There are tens of thousands of Internet network providers and we make an effort to track as many as we can, but we have less coverage for niche and local providers. The following is a sample of NTP Time IP addresses on this type of network.

ASN Description	ASN	Route	Location	IP
Selectel - Moscow	AS50340	5.35.10.0/23	Russia	5.35.11.156

and 1730 more

Hosting

Cloud hosting vendors like AWS and Microsoft Azure provide cloud-based computing and network resources to deliver applications. The hosting platforms used by NTP Time are summarized below by geographical points-of-presence (PoP). Each PoP can host many IPs to deliver an application.

Content Delivery Networks - CDNs

In order to get information to end users more quickly, many applications are distributed from multiple geographical points-of-presence (PoPs) using Content Delivery Networks (CDNs). Each PoP can host many IPs to deliver an application. A sample IP is provided.

Take special note of CDNs that use Anycast technology. Anycast makes it possible to route a single IP address to a variety of different geographic locations. In other words, one global Anycast IP is hosted in multiple geographic locations.
