1. http://freedns.afraid.org

2. 좌측 메뉴 DynamicDNS 클릭

3. 로그인

4. Programmer's XML API 클릭

5. ASCII를 클릭하면 소유한 URL별 API Interface URL을 확인 할수 있다. 이것을 복사한다. 

6. Mikrotik 장비에서 System > Scripts 에서 아래 스크립트를 신규 작성 추가한다.

주의! : URL 문자열에 음표(?)가 있을 텐데 이것 앞에 '\'를 추가해주어야만 한다.

# Specify the "Direct URL", which is https://freedns.afraid.org/dynamic/

# If RouterOS version 5.xx, then remove from the URL encryption - "https" change this to "http". Also see below.

# In front of the sign "?" put a backslash "\".

:global "direct-url" "http://API_URL"

# Specify the URL API "ASCII"

# Log in under your account and open the page https://freedns.afraid.org/api/

# Then copy the URL of your site - Available API Interfaces : ASCII (!!! NOT XML !!!)

# ATTENTION!!!! Before the question mark, put a backslash "\".

# If RouterOS version 5.xx, then remove from the URL encryption - "https" change this to "http".

:global "api-url" "http://API_URL"

# Specify your domain or subdomain.

:global "dns-domain" "갱신하고자 하는 URL, 예, mine.mooo.com"

# Define variables for the external (WAN) interface

# Case sensitive.

:global "out-interface" "Mikrotik 장비의 인터넷 인터페이스 이름, 예, ether1"

# !!!!!!!!!!!!!!!!! Nothing more do not need to edit!!!!!!!!!!!!!!!!!

# Check whether the file with the IP domain - freedns.txt

:if ([:len [/file find name=freedns.txt]] > 0) do={

} else={

/tool fetch url=$"api-url" dst-path="/freedns.txt"

}

# Split the file

:local "result" [/file get freedns.txt contents]

# Compare the external IP with the IP address of the DNS domain.

:if ($"current-ip" != $"dns-domain-ip") do={

# If different, then sent to freedns.afraid.org our external IP by using Direct URL

:log info ("Service Dynamic DNS: old IP address $"dns-domain-ip" for $"dns-domain" CHANGED to -> $"current-ip"")

/tool fetch url=$"direct-url" keep-result=no

# Download the file with the new IP after 5 sec.

:delay 5

/tool fetch url=$"api-url" dst-path="/freedns.txt"

} else={

# Not to clog the log, you need to comment out this line.

:log info ("IP address is NOT CHANGED, the update is not required")

}
