It looks like you are using the name servers with the IP addresses 220.127.116.11 and 18.104.22.168. Can you ping those addresses for the command line?Since you obfuscated the IP addresses in the n... [by hawkmage]
Now that web hosts are starting to provide IPv6 addresses in addition to IPv4 (or in a few cases, instead), I am finding myself puzzled as to what number of addresses are actually allocated.
As I understand it, IPv6 addresses are meant to be allocated in /64 blocks, theoretically giving some 1.8*10^19 addresses - though in fact the variable part of these addresses seems usually to consist of the
I upgraded to 12.10 yesterday and now I can't seem to resolve domain names. Connection Information seems to provide proper DNS server addresses from DHCP, but "ping" and "nslookup" both immediately fail with "unknown host" errors. I have tried external servers (google.com, ubuntu.com) as well as internal network host names, and none work.
So here's my conundrum. I have Comcast business internet with 5 static IP addresses to host a few servers. Servers that I no longer am running. I'd like to drop the static addresses so I can save $20 a month AND so that I can use my own modem (Comcast forces you to RENT their modem to use static addresses for $12.95 PER MONTH) for a total substantial savings of ~$33 per month.
I would like to be able to ping several IP addresses simultaneously from an android app. I've written the code below and want to be able to call my "Ping Something" method multiple times on different threads. If I do this as is at the moment the results all interfere with each other and basically the thread that runs last overwrites all the others.
As I understand from the ISO-OSI model, MAC addresses operate on a different layer than IP addresses. This is clear to me.
I can accept that Ethernet (LAN) just does not make use of IP addresses to do communication, but uses MAC addresses. I understand that these MAC addresses cannot be used for routing outside of a LAN, as they are not hierarchically defined.
