Renew A Domain


  • When should you renew your domain?

Upon successful registration, a domain name shall be deemed to have been registered in the name of the registrant as of the date on which such registration had been applied for, and the said registration shall expire in one or multiple years respectively from such date.

Prior to the Expiry Date, the registrant of a domain name may upon payment of the requisite fee extend its period of registration by either one, two, five or ten years beyond the then current Expiry Date.

  • How do you renew your domain?

Registrants may register a domain name for an initial period of either 1,2, 5 or 10 years. You will get discounts when you register for more than one year at once.(view price details here)

  • What will happen if you do not renew your domain on time?

In the case of domain names that are not renewed on or before the Expiry Date or within a specified time period decided by LK Domain, immediately following the Expiry Date (“the Post Expiry Grace Period”), the domain name will be suspended. 

IMPORTANT!
If the domain has expired, you are required to regularize your account by settling the arrears annual subscriptions which enable you to renew your domain and claim multiple year discounts. Please contact the customer services hotline for more information.

 

Domain Suspension:

The existing server details of the particular domain name are removed temporarily and pointed to LK Domain Registry servers so that when a person browses the particular web address, he/she will be directed to a web page which says that the domain name has been temporarily disconnected.

 

Domain Name Deletion

The original registrant may reactivate the domain name during the suspension period by settling all outstanding dues. If they fail to do so, the domain name will be deleted after a reasonable time as decided by the Registry. 

 

  • Will you lose your domain forever?

Interested parties can request for an expired domain name (only during the period in which the domain name is SUSPENDED) via the particular suspended website. As per our normal procedure, domain names may be re-categorized into higher priced categories (Desirable or Special Domain Names) before being SUSPENDED.

At the expiry of the suspension period:

• If customers have placed their interest in registering the suspended domain, LK Domain Registry will inform them and register the domain according to the order they placed their interest.

• If no requests have been received, the domain name will be released to the general public.

1. Introduction

This document sets out the policy for IDN (Internationalized Domain Names) registrations under.ලංකා and .இலங்கை at LK Domain Registry. This policy and procedure are designed to ensure reliable and reasonable assignments of IDN for the registrants.

2. Abbreviations

Character: Character can be either a vowel, or a consonant or a composite ( a consonant with a vowel modifier) in Sinhala/Tamil script, or a digit/number or a Latin letter or hyphen(-)

Domain name: Domain name is unique address that can be used identify a resource on the Internet. It may consist one or more domain labels.

Domain Label: Domain label is a string which is bounded by period(s) “.”

Ex: nic.lk in this Domain name “nic” is a domain label

3.2. IDN Policy

3.2.1.       Registrants can request IDN domains under.ලංකා and .இலங்கை in LK Domain Registry.

3.2.2.      The requested domain name should consists only the characters given in the relevant IDN language table [Appendix-A]. The relevant language table for. ලංකා and . இலங்கை are attached in the Appendix A.

E.g.: If you are registering a   .ලංකා domain name, then you should use characters which are included in the.ලංකා language table.

3.2.3.      The domain string must contain at least two letters.

3.2.4.      The string should consist valid Unicode code points and should comply with the linguistic rules of the respective language. However it does not need to comply with the spelling rules.

E.g.:

ෙඅ is not a valid string.

නය and ණය are valid strings and which are considered as two different strings.

3.2.5.      The String should not contain the pattern “xn- -”

3.2.6.      It you are requesting a domain name containing zwj(200D) we are registering two domain names. They are domain name which contains zwj and a domain name without zwj as a bundle.

  • Even if we register two domain names the domain registration charges will not be affected.

E.g.:

If you are requesting a .ලංකා domain, containing ් + ර or ්+ය we are registering an extra domain name contains rakaransaya(්‍ර) or yansaya(්‍ය) with the requesting domain accordingly.

E.g.:  If you are requesting සත්‍ය.ලංකා we are registering සත්ය.ලංකා domain as well.

සත්‍ය.ලංකා        සත්ය.ලංකා

4. IDN Label Rules

This set of rules (Appendix-B) guide you to create a valid domain name for.ලංකා and. இலங்கை domains.

  • Rules

# Rules have the following format:

# <sequence>:<result>

# Key:

# <sequence> is the sequence of characters starting from the current position in the label where each element is either a named character or a member of a character set defined above.

# <result>  is either "fail" or "next"

# Logically, a label is processed by iterating through its character positions

# In each iteration, each rule is checked with the substring starting from the current character position.

# If the current substring matches then the result is applied as follows:

#   fail: stop, the label is invalid

#   next: move to the next character position

# If the processing reaches the end of the string, then the label is valid.

#

# Variants:

# A variant is defined by a rule of the form

# <sequence1> | <sequence2> : variant

# If the current substring matches either <sequence1> or <sequence2>, then note that

#    the label contains a variant, and then move to the next character position.

# Rule can be defined as follows.

1. First letter can be a vowel a consonant a digit or a English letter

EX: Sinhala_Letter_A(0D85). . . . Sinhala_Letter_AU(0D96)

Sinhala_Letter_KHA(0D9A) ... Sinhala_Letter_FA(0DC6)

English_Letter (A – Z or a - z)

5.2.2. IDN Label Rules for .இலங்கைdomains

  • IDN rules for Indic scripts are based on strings rather than individual Unicode characters
  • as Indic letters (akshara) are represented by strings of Unicode characters.
  • we define the sets (consonants, vowels, vowel signs, etc.) to which we group the letters

  • Rules

# Rules have the following format:

# <sequence> : <result>

# Key:

# <sequence> is the sequence of characters starting from the current position in the label

#    where each element is either a named character or a member of a character set defined above.

# <result> is either "fail" or "next"

# Logically, a label is processed by iterating through its character positions

# In each iteration, each rule is checked with the substring starting from the current character position.

# If the current substring matches then the result is applied as follows:

#   fail: stop, the label is invalid

#   next: move to the next character position after the end of the matched string

# If the processing reaches the end of the string, then the label is valid.

# Variants:

# A variant is defined by a rule of the form

# <sequence1> | <sequence2> : variant

# If the current substring matches either <sequence1> or <sequence2>, then note that

#    the label contains a variant, and then move to the next character position.

# we now define each of the special cases, and finally the general rules.

# allow ik + ssa as either a single glyph (க்ஷ) or separate glyphs (க்‌ஷ)

# these are variants of each other

# NOTE GD-20100416: we could also allow just one form, and make the other invalid

# This is the only place where ZWNJ is valid

Tamil_Letter_KA Tamil_Sign_Pulli Tamil_Letter_SSA | Tamil_Letter_KA Tamil_Sign_Pulli ZWNJ Tamil_Letter_SSA : variant

# the ZWNJ is not valid anywhere else except in the sequence2 above

ZWNJ : fail

# disallow old form of Shri (ஸ+்+ர+ீ)

Tamil_Letter_SA Tamil_Sign_Pulli Tamil_Letter_RA Tamil_Vowel_Sign_II

: fail

# Note: the valid representation of Shri is

# Tamil_Letter_SHA Tamil_Sign_Pulli Tamil_Letter_RA Tamil_Vowel_Sign_II (ஶ+்+ர+ீ)

# we don't need a special rule for this

# disallow a LLA after a consonant with a Kombu (e.g. கெ ள) unless it is modified by a vowel sign or Pulli

#    to avoid confusion with TamilConsonant+Vowel Sign AU

# It is presumed that this sequence will never occur in a valid word

# the kombu should be preceeded by a consonant

TamilConsonant Tamil_VowelSign_E Tamil_Letter_LLA TamilVowelSign : next

TamilConsonant Tamil_Vowel_Sign_E Tamil_Letter_LLA Tamil_Sign_Pulli : next

TamilConsonant Tamil_Vowel_Sign_E Tamil_Letter_LLA : fail

# disallow a LLA after Letter O (ஒ ள) unless it is modified by a vowel sign or Pulli

#   to avoid confusion with Letter AU (ஔ)

# again, we assume that this sequence will never occur in a valid word

Tamil_Letter_O Tamil_Letter_LLA TamilVowelSign : next

Tamil_Letter_O Tamil_Letter_LLA Tamil_Sign_Pulli : next

Tamil_Letter_O Tamil_Letter_LLA : fail

# General Rules

# a vowel sign or a pulli (virama) can only follow a consonant and is not valid elsewhere

TamilConsonant TamilVowelSign : next

TamilConsonant Tamil_Sign_Pulli  : next

TamilVowelSign : fail

Tamil_Sign_Pulli : fail

# allow consonants, vowels, Aytham, European numerals anywhere (unless disallowed by previous rules)

TamilConsonant : next

TamilVowel : next

Tamil_Sign_Aytham : next

ASCIIDigit : next

Hyphen-Minus : next

# IDN rules, which are not implemented in this table, restrict the placement of hyphen-minus

# anything else is invalid

: fail
