IP addresses play a crucial role in the architecture of the Internet. Internet Protocol version 4 (IPv4) was originally developed for this purpose and has successfully managed data traffic on the Internet for many years. However, with the constantly growing number of IP addresses required, IPv4 reached its limits. To meet these challenges and support the future development of the Internet, Internet Protocol Version 6 (IPv6) was introduced. As a renowned university, RWTH Aachen University strives to keep pace with this development. For this reason, we are planning to commission the license servers for software via IPv6.*<\/p>\n<p>&nbsp;<\/p>\n<p><!--more--><\/p>\n<p>&nbsp;<\/p>\n<h3><span style=\"color: #00549f;\">Background<\/span><\/h3>\n<p>IPv4 addresses consist of 32 bits. Therefore, a maximum of 4 billion addresses can be formed, which ultimately led to a shortage of addresses. The Internet Protocol Version 6 (IPv6) was created in response to this address shortage. The IPv6 consists of 128 bits. It enables the unique assignment of IP addresses for every device in the world.<\/p>\n<p>The transition to this new protocol was initially slow, as only a few applications, hosts and networks initially offered the necessary support. However, we are now seeing a significant shift as both leading technology providers and service providers make the transition.<\/p>\n<p>&nbsp;<\/p>\n<h3><span style=\"color: #00549f;\">What is changing?<\/span><\/h3>\n<p>From February 16, 2024, RWTH will start a beta operation for the license servers for software over IPv6. The license servers can be reached via a new additional Fully Qualified Domain Name (FQDN), which is communicated when the software is purchased.<\/p>\n<p>With some programs, it can happen that the direct entry of the FQDN is not resolved correctly despite being entered. In this case, the IPv6 address of the license server must be entered. A list of license servers that are currently accessible under IPv6 can be found on <a href=\"https:\/\/help.itc.rwth-aachen.de\/en\/service\/u7okrwv9h0s2\/article\/9b855b1bebb342399da2a0319379c136\/\">IT Center Help<\/a>.**<\/p>\n<h3><\/h3>\n<h3><span style=\"color: #00549f;\">Limitations in beta operation<\/span><\/h3>\n<p>Only license servers that have been successfully tested for IPv6 compatibility are included in beta operation. In the case of FlexLM, for example, a widely used license management system used by various software manufacturers, IPv6 is already supported by the main component. However, it is up to each manufacturer to decide how this component is implemented in their own license software. Therefore, not all license servers based on FlexLM are automatically compatible with IPv6. This leads to technical hurdles for some license servers, which are due to a lack of implementation on the part of the software manufacturers.<\/p>\n<p>&nbsp;<\/p>\n<h3><span style=\"color: #00549f;\">Prospects<\/span><\/h3>\n<p>Hosted license servers are excluded in this limited beta. We are aware that this does not cover some widely used software products. We are already in active contact with the manufacturers in order to overcome these challenges. However, due to the technical circumstances of the individual license servers, we are unable to provide an exact date or a concrete forecast at this time.<\/p>\n<p>&nbsp;<\/p>\n<hr \/>\n<p>Responsible for the content of this article are <a href=\"https:\/\/www.itc.rwth-aachen.de\/cms\/it-center\/it-center\/profil\/team\/~epvp\/mitarbeiter-campus-\/?gguid=0x2C5E1B0A3DA32A45AB293A42E93EEC07&amp;allou=1&amp;lidx=1\">St\u00e9phanie Bauens<\/a> and <a href=\"https:\/\/www.itc.rwth-aachen.de\/cms\/it-center\/it-center\/profil\/team\/~epvp\/mitarbeiter-campus-\/?gguid=PER-UCGTEXE&amp;allou=1&amp;lidx=1\">Weng Gyang<\/a>.<\/p>\n<h6>* The paragraph was updated on 20.02.2024.<br \/>\n** The paragraph was updated on 20.02.2024.<br \/>\nNote: The headline was also updated on 20.02.2024.<\/h6>\n<p><\/p>","protected":false},"excerpt":{"rendered":"<p>Sorry, this entry is only available in Deutsch.<\/p>\n","protected":false},"author":2228,"featured_media":18538,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"c2c_always_allow_admin_comments":false,"footnotes":""},"categories":[306,315],"tags":[1088],"class_list":["post-18536","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-ankuendigungen","category-services-support","tag-ipv6"],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/blog.rwth-aachen.de\/itc\/en\/wp-json\/wp\/v2\/posts\/18536","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/blog.rwth-aachen.de\/itc\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/blog.rwth-aachen.de\/itc\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/blog.rwth-aachen.de\/itc\/en\/wp-json\/wp\/v2\/users\/2228"}],"replies":[{"embeddable":true,"href":"https:\/\/blog.rwth-aachen.de\/itc\/en\/wp-json\/wp\/v2\/comments?post=18536"}],"version-history":[{"count":7,"href":"https:\/\/blog.rwth-aachen.de\/itc\/en\/wp-json\/wp\/v2\/posts\/18536\/revisions"}],"predecessor-version":[{"id":18662,"href":"https:\/\/blog.rwth-aachen.de\/itc\/en\/wp-json\/wp\/v2\/posts\/18536\/revisions\/18662"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/blog.rwth-aachen.de\/itc\/en\/wp-json\/wp\/v2\/media\/18538"}],"wp:attachment":[{"href":"https:\/\/blog.rwth-aachen.de\/itc\/en\/wp-json\/wp\/v2\/media?parent=18536"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/blog.rwth-aachen.de\/itc\/en\/wp-json\/wp\/v2\/categories?post=18536"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/blog.rwth-aachen.de\/itc\/en\/wp-json\/wp\/v2\/tags?post=18536"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
