Due to growth in customer numbers, we need to change to a new IP network at DE-CIX Munich. This means that all existing customers will have to change their router’s IPv4 address – and all IPv4 BGP peering sessions. The network change only affects IPv4 addresses; IPv6 addresses do not need to be changed.
Previously we have done this change successfully in Dusseldorf and in Madrid.
The renumbering will take place on 27- 29 July
The change will take place over three days between 27 and 29 July 2021. More details have been shared with the DE-CIX Munich customers via email.
A new /23 network
We have connected over 200 routers to DE-CIX Munich’s peering LAN. As the peering LAN currently uses a /24 network which contains 254 IPv4 addresses, we need to change to a new IP network. Therefore, we have acquired a new address range, a /23 network containing 510 IPv4 addresses for customer routers.
When DE-CIX Munich first launched, it was not possible to get such a large network. But, as an Internet Exchange, a critical infrastructure, we are able to get more addresses if we can show that we need them; and with our current growth, we were able to get a new /23 network for Munich. The new network, however, is not adjacent to our current one and we will be getting a completely new /23 network. Therefore, all customers will have to renumber their IPv4 interface connecting to the Munich peering LAN.
