SaaS - Software-as-a-Service

Applications often use various third party platforms for providing authentication, advertising, cybersecurity, e-mail services and more. The Software-as-a-Service (SaaS) platforms used by Nextdoor are summarized below.

SaaS solutions are often deployed on multiple IPs across different geographical points-of-presence. In addition, it is common for these IP addresses to be shared by multiple applications.

SaaS	# of IPs
HubSpot	4
Medium	12
Salesforce	57
SendGrid	43

Service	Category	Sample IP	IP Count
HubSpot	Advertiser	199.60.103.28	4 IPs
Medium	Business	52.0.16.118	12 IPs
Salesforce	Advertiser	51.112.11.195	57 IPs
SendGrid	Mail	149.72.166.117	43 IPs

Hosting

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

Cloud Hosts	# of IPs
Amazon AWS	146
WP Engine	2
Google Hosted	8
DigitalOcean	1

Host	PoP	Location	IPs
DigitalOcean	San Francisco	United States	1 IP
WP Engine	Charleston	United States	1 IP
WP Engine	Anycast	Global	1 IP

Amazon AWS	Sydney	Australia	18 IPs
Amazon AWS	Dublin	Ireland	23 IPs
Amazon AWS	Columbus	United States	12 IPs

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.
