IGEL License Portal (ILP) Migration 2021
On April 22nd, 2021, IGEL will migrate the IGEL License Portal (ILP) and its infrastructure to a highly available and scalable cloud platform. While IGEL will keep service interruptions to a minimum, we advise our customers not to plan large rollouts of new licenses on April 22nd and 23rd.
The migration happens via three DNS entry changes. The propagation of these DNS changes throughout the internet can take from an hour to 72 hours.
DNS Name | Component | Old IP Address | New IP Address |
Web frontend for customers | 194.76.156.73 | Eastern US (for North America) 52.186.108.205 | |
susi.igel.com | Interface for UMS Server | 194.76.156.60 | 51.105.196.76 |
On your local workstation or UMS Server, you can flush the DNS cache with the following commands:
- Windows Workstation:
ipconfig /flushdns- Powershell:Clear-DnsClientCache - Windows DNS Server:
dnscmd /clearcache- Powershell:Clear-DnsServerCache - Linux:
sudo /etc/init.d/nscd restart - Systemd Resolved (e.g. IGEL OS):
sudo systemd-resolve --flush-caches - DNSMasq:
sudo systemctl restart dnsmasq.service - Nscd:
sudo systemctl restart nscd.service - Mac OS Sierra, El Capitan, Mavericks, Mountain Lion, Lion:
sudo killall -HUP mDNSResponder - Mac OS X Yosemite:
sudo discoveryutil udnsflushcaches - Mac OS X Snow Leopard:
sudo dscacheutil -flushcache - Mac OS X Leopard and below:
sudo lookupd -flushcache
Firewalling
If you restrict the internet access of the UMS server to certain IP addresses, make sure to allow 51.105.196.76, the new address of the SUSI service.
