| ICMPv6 (Internet Control Message Protocol for version 6) – tai interneto kontrolės žinučių protokolas,kurį naudoja IPv6. Ankstesnis protokolas IPv4 naudoja ankstesnį kontrolės žinučių protokolą- ICMP. ICMPv6, kaip ir ICMP priklauso TCP/IP protokolų šeimai ir yra priskiriamai OSI tinklo sluoksnio protokolams. Protokolas neturi jokio gavimo patvirtinimo funkcijos, todėl laikomas nepatikimu. Pagrindinė protokolo paskirtis - perduoti klaidos informaciją duomenų siuntėjui. Informacija dažniausiai perduodama tarp prie tinklo prijungto kompiuterio ir tinklinės įrangos, pvz., maršrutizatoriaus. Galimų klaidų pavyzdžiai: nutolusios aptarnavimo stoties prievadas yra nepasiekiamas arba maršrutizatorius nežino, kaip pasiekti gavėjo tinklą. ICMPv6 paplidytas klaidų žinutėmis,pavyzdžiui, “Paketas per didelis” ir grupės valdymo funkcijomis (multicast). Protokolas taip pat naudojamas atlikti užklausas. | ICMPv6 (Internet Control Message Protocol for version 6) – tai interneto kontrolės žinučių protokolas,kurį naudoja IPv6.

| Plačiausiai žinomi ICMP pritaikymai yra programos ping ir traceroute. ICMPv6 antraštės sudėtis: Tipas (8 bitai, nurodo žinutės formatą), Kodas (8 bitai. Tolimesnė ICMPv6 tipo specifikacija), Duomenų patikros suma (16 bitų. Skaičius naudojamas patikrinti, ar gautos ICMP žinutės turinys yra nepakitęs). |

ICMPv6
Apibrėžimas
ICMPv6 (Internet Control Message Protocol for version 6) – tai interneto kontrolės žinučių protokolas,kurį naudoja IPv6. Ankstesnis protokolas IPv4 naudoja ankstesnį kontrolės žinučių protokolą- ICMP. ICMPv6, kaip ir ICMP priklauso TCP/IP protokolų šeimai ir yra priskiriamai OSI tinklo sluoksnio protokolams. Protokolas neturi jokio gavimo patvirtinimo funkcijos, todėl laikomas nepatikimu. Pagrindinė protokolo paskirtis - perduoti klaidos informaciją duomenų siuntėjui. Informacija dažniausiai perduodama tarp prie tinklo prijungto kompiuterio ir tinklinės įrangos, pvz., maršrutizatoriaus. Galimų klaidų pavyzdžiai: nutolusios aptarnavimo stoties prievadas yra nepasiekiamas arba maršrutizatorius nežino, kaip pasiekti gavėjo tinklą. ICMPv6 paplidytas klaidų žinutėmis,pavyzdžiui, “Paketas per didelis” ir grupės valdymo funkcijomis (multicast). Protokolas taip pat naudojamas atlikti užklausas.
