Request for Proposal: IMRS Cluster (Singapore) Network Connectivity

LOS ANGELES – 23 December 2019 – The Internet Corporation for Assigned Names and Numbers (ICANN) is seeking one or more vendors to provide Internet access for a new ICANN Managed Root Server (IMRS) location in Singapore.

As part of the service provided to the Internet community, ICANN operates one of the 13 root servers of the Internet, the IMRS, also known as "L.ROOT-SERVERS.NET".

The ICANN organization has established the need to continue to expand the IMRS by installing a cluster in Singapore, resulting in increased root server capacity for the Asian region and resulting in increased resiliency of not just the IMRS, but the entire Root Server System.

Indications of interest must be emailed to by 23:59 UTC on 10 January 2020. Complete proposals must be electronically submitted by 23:59 UTC on 31 January 2020 using the ICANN org sourcing (RFP) tool. Access to the tool will be granted after receipt of an indication of interest to the email address above.


ICANN's mission is to help ensure a stable, secure, and unified global Internet. To reach another person on the Internet, you need to type an address – a name or a number – into your computer or other device. That address must be unique so computers know where to find each other. ICANN helps coordinate and support these unique identifiers across the world. ICANN was formed in 1998 as a not-for-profit public-benefit corporation with a community of participants from all over the world.

Domain Name System
Internationalized Domain Name ,IDN,"IDNs are domain names that include characters used in the local representation of languages that are not written with the twenty-six letters of the basic Latin alphabet ""a-z"". An IDN can contain Latin letters with diacritical marks, as required by many European languages, or may consist of characters from non-Latin scripts such as Arabic or Chinese. Many languages also use other types of digits than the European ""0-9"". The basic Latin alphabet together with the European-Arabic digits are, for the purpose of domain names, termed ""ASCII characters"" (ASCII = American Standard Code for Information Interchange). These are also included in the broader range of ""Unicode characters"" that provides the basis for IDNs. The ""hostname rule"" requires that all domain names of the type under consideration here are stored in the DNS using only the ASCII characters listed above, with the one further addition of the hyphen ""-"". The Unicode form of an IDN therefore requires special encoding before it is entered into the DNS. The following terminology is used when distinguishing between these forms: A domain name consists of a series of ""labels"" (separated by ""dots""). The ASCII form of an IDN label is termed an ""A-label"". All operations defined in the DNS protocol use A-labels exclusively. The Unicode form, which a user expects to be displayed, is termed a ""U-label"". The difference may be illustrated with the Hindi word for ""test"" — परीका — appearing here as a U-label would (in the Devanagari script). A special form of ""ASCII compatible encoding"" (abbreviated ACE) is applied to this to produce the corresponding A-label: xn--11b5bs1di. A domain name that only includes ASCII letters, digits, and hyphens is termed an ""LDH label"". Although the definitions of A-labels and LDH-labels overlap, a name consisting exclusively of LDH labels, such as"""" is not an IDN."
