When moving web host to another hosting service¡¯s server or changing the server¡¯s IP address, one of the important consideration to ensure to continue availability of the websites hosted on the server, minimize the downtime of the web sites, avoid weird problems such as emails get delivered to either server randomly, or browsing at old server, is how fast DNS (Domain Name System) will be able to translate or resolve hostname or domain name into your new IP address, instead of the old IP destination. ´Ù¸¥ È£½ºÆÃ ¼ºñ½ºÀÇ ¼¹ö ¶Ç´Â ¼¹öÀÇ IP ÁÖ¼Ò, ÇϳªÀÇ À¥ »çÀÌÆ®ÀÇ °¡¿ë¼ºÀ» º¸ÀåÇϱâ À§Çؼ´Â °è¼ÓÇØ¼ Áß¿äÇÑ °í·Á »çÇ×ÀÇ º¯È¸¦ ¿òÁ÷ÀÌ´Â À¥ È£½ºÆ® ¼¹ö¿¡, ÀÌ»óÇÑ ¹®Á¦°¡ ¹ß»ýÇÏÁö ¾Êµµ·Ï À¥ »çÀÌÆ®ÀÇ ´Ù¿î ŸÀÓÀ» ÃÖ¼ÒÈÇϴ ȣ½ºÆÃ µî ¹ø¿ª ¶Ç´Â ±ÍÇÏÀÇ »õ IP ÁּҷΠȣ½ºÆ® À̸§ ¶Ç´Â µµ¸ÞÀÎ À̸§À» ÇØ°áÇÏ´Â ´ë½Å ±âÁ¸ IP ¸ñÀûÁö ¼öÀÖÀ» °ÍÀÌ´Ù ¹«ÀÛÀ§·Î À̸ÞÀÏ Áß Çϳª¸¦ ¼¹ö·Î Àü´Þ¹ÞÀ» ¶Ç´Â ±âÁ¸ ¼¹ö¿¡¼ ºê¶ó¿ì¡, ¾ó¸¶³ª »¡¸®¿¡¼ DNS (Domain Name System)¿¡ÀÖ´Ù.

DNS works in such as a way that when a request for IP address received by DNS resolver, it will then query the root servers to find the authoritative server with detailed knowledge of the particular domain name.

If a valid IP address for the domain is returned by the authoritative server, the DNS resolver will cache the DNS resolution for a given period of time known as TTL (Time To Live) after a successful answer, in what known as DNS caching in order to reduce the load on particular DNS server.

DNS caching allows resolution of domain name to IP to take place locally using the cached information instead of querying the remote server for subsequent requests, until the TTL duration expires.

The Time-To-Live (TTL) timer is the trick to ensure that the DNS cache expires quickly and always stays fresh.

TTL is defined by domain administrator in the authoritative DNS server for the zone where data originates, and its values instruct DNS caching resolvers to expire and discard the DNS records after TTL seconds.

The tweaking of TTL in DNS records must be done a few days before it¡¯s about to change (date of server moving or IP change) to ensure that all DNS caching resolvers receives the new TTL value and expires the old longer value. ±×°Í¿¡ ´ëÇØ À̵¿À̳ª IP¸¦ º¯°æÇϱâ Àü¿¡ ¼¹öÀÇ (³¯Â¥¸¦ º¯°æÇÏ´Â ¹æ¹ý DNS ·¹Äڵ忡¼ TTLÀº ¸î Àϰ£ÀÇ Á¶Á¤) ¸ðµç DNS ij½Ì »õ·Î¿î TTL °ªÀ»¹Þ½À´Ï´Ù resolvers ¿¾ °¡Ä¡¿Í ÀÌ»óÀÌ ¸¸·áµÇµµ·Ï ÀÌ·ç¾îÁ®¾ßÇÕ´Ï´Ù.
