List of IP addresses

A list of Static IP addresses are below for each region.  A DNS lookup will show all available static IPs.

Simple FTP Server

static-sfs-ap-southeast-2.docevent.io

  • 52.64.77.113
  • 3.105.157.166
  • 13.210.63.82

static-sfs-eu-west-1.docevent.io

  • 34.249.236.182
  • 108.128.155.118
  • 34.246.77.238

static-sfs-us-east-1.docevent.io

  • 3.213.216.51
  • 3.219.3.70
  • 3.216.131.83
  • 3.219.98.225
  • 35.173.159.53
  • 35.175.92.86

Why are there multiple IPs per region?

Our load balancer provides one IP address per AWS availability zone, if you use a single IP and on the rare chance that this availability zone becomes unavailable then no connections will be accepted.  We still recommend you use the DNS name at all times.

Static IPs and FTP/S caveats

  1. When using FTP/S the initial connection is made to the above static IPs, however when transferring files using passive mode our server will request the client to connect to another passive FTP port on another IP address.  These IP addresses are dynamic because of auto-scaling policies.  These passive IP addresses will change.
  2. If your FTP client does not correctly parse the FTP PASV response from our server it may attempt to incorrectly connect to the static IPs.  In this case you should connect to the direct dynamic IP addresses, you can do so by prefixing direct- to the DNS name, for example using the DNS direct-sfs-us-east-1.docevent.io will connect to the dynamic DNS IPs.
  3. If your client uses the EPSV command instead of EPRT or PASV, the static IPs will fail because the client will attempt to connect on a new data connection directly to the load balancer.  If using a static IP we recommend you disable the EPSV command on your client.
