Our customers often ask us about the list of IP addresses of our servers so that they can whitelist them on their mail servers. However our cloud periodically change the number of application servers so it is not possible to give you a fixed list of IP addresses valid for years.
Therefore the easiest way to get the most up to date list of our IP addresses is from the TXT / SPF DNS record of our _spf.ladesk.com domain, so please open >>>>> this link <<<<< and the list of our IP addresses will appear in a green box in a few seconds as seen here:
The listed IP addresses of our application servers are used to access external services from our cloud like for example Facebook API, SMTP servers, POP3 servers, IMAP servers, API calls from plugins, old Twilio calls etc.)
