'''National Knowledge Network''' '''(NKN)''' is a multi-gigabit<ref>[[Gigabit Ethernet]]</ref> [[national research and education network]], whose purpose is to provide a unified high-speed network backbone for educational and research institutions in [[India]]. The network is managed by the [[National Informatics Centre]].
== Details ==
The NKN is a hierarchical network divided into three basic layers – ultra-high speed CORE (multiples of 10 Gbit/s; Level 1), Distribution (Level 2), and Edge (speeds of 1 Gbit/s or higher; User Level). Depending on the type of connectivity required by the user organization, geographical presence, and the location of [[Point of presence|Point of Presence]] (PoP) of NKN, (belonging to Core and Distribution), connectivity would be provided to the institutes. NKN backbone will typically have 18 Core PoPs and around 25 Distribution PoPs across the country. Multiple bandwidth providers will create the NKN backbone and any service provider can provide the edges.
The network is designed to support Overlay Networks, Dedicated Networks, and Virtual Networks. Advanced applications in areas such as Health, Education, Science & Technology, [[Grid Computing]], [[Bioinformatics]], [[Agriculture]], and [[Governance]] will be an integral part of NKN. The entire network will seamlessly integrate with the global scientific community at multiple [[gigabit]]s per second speed.
=== IP and ASn resources ===
National Knowledge Network has got the following resources from [[APNIC]] ([[Regional Internet registry]] for Asia-Pacific Region).
[[IPv6]] Segment—
# 2405:8A00::/32

=== IPv6 implementation ===
NKN has got 2405:8A00::/32 [[IPv6]] block from [[APNIC]] ([[Regional Internet registry]] for Asia-Pacific Region) and allocating /48 block to every connected member institution.<ref>{{cite web|url=http://nkn-india.blogspot.in/2013/11/internet-protocol-version-6-ipv6-status.html|title=v6 status in NKN}}</ref>
/48 is allocated to the connected member so that the member institute can do [[multihoming]], if required.
=== DNSSEC ===
NKN is [[DNSSEC]] enabled.<ref>{{cite web|url=http://nkn-india.blogspot.in/2013/11/dnssec-status-in-nknin-domain.html |title=DNSSEC status in NKN}}</ref><ref>{{Cite web|title=nkn.in {{!}} DNSViz|url=https://dnsviz.net/d/nkn.in/dnssec/|access-date=2020-07-23|website=dnsviz.net}}</ref>
