IP 224.0.0.22 => larm

[grer]

Min brandvägg larmar ideligen om att IP nr 224.0.0.22 gärna vill ha något för sig - men blir dessbättre hindrat av samma brandvägg...

 

Vad vill dom?

Googlade lite http://www.google.se/search?hl=sv&q=%22224.0.0.22%22&btnG=Google-s%C3%B6kning&meta=

 

Hittade bland annat detta svar på ungefär samma fråga på ett annat forum:

 

"the 224.x.x.x signifies that it is a multicast address.

the IGMP is Internet Group Membership Protocol.

This is can be caused by your machine advertsing to the router on the segment that you are on that it wants to join a multicast group.

It's basically used by IP hosts to report their multicast group membership to an adjacent router.

laymans terms, your machine says "hey, I'm a member of this multicast group, even though I can also see another router"

 

It could be triggered by a topology change in the network upstream from you, or when the router closest to where you are connected updates it's routing tables and sends out a request to see who all can see it after the change.

I don't think it's anything to worry about.

Nåväl, efersom jag inte haft några egentliga problem med detta, annat än att brandväggen larmar i samband med start av datorn, så kan man ju lugnt låta det hela bero...

 

Vore intressant att få veta om någon haft några påtagliga problem med/av IP 224.0.0.22...
