Looks like ARIN is (almost) out of IPv4 space. When I checked they had 88 /23 and 440 /24 networks left.
A story I was told recently and loosely related to todays other post
Boss is telling one of his admins that there is plenty of time to implement IPv6. At least a couple of years. A week later one of their sales people sold IPv6 support to a big customer.
I’ve been saying it for years: “Even if you don’t implement IPv6 right away make sure that new hard- and software you are buying supports IPv6.”
In the last couple of month I hear lot of complaints: “We can’t do IPv6. We just bought $product last year and it does not support IPV6.”
Sometimes I like to know if a given domain uses IPv6 (and DNSSEC).
I finished a small shell script last week to automate this task.
jens@screen:~/check_dns.git$ ./check_dns.sh quux.de
Domain has DNSSEC
Host has at least one AAAA record
At least one nameserver has an AAAA record
At least one MX has an AAAA record
Maybe I’ll add some checks to see if those IPv6 addresses are really accessible.
I’m just working on a distributed Icinga2 setup (I’ll write more about it later this month). There is a lot SNMP monitoring involved an today I tried to get some MIBs
1. Why do I need an account (and probably a support contract) to download MIBs?
2. Naming an archive mib.zip is a stupid idea. I now have several files with the same name. All from different vendors.
3. Advertising SNMP and then only returning sysUptime, sysLocation, etc. is also ….
And another one for the wall of shame:
[jens:~] $ host forge.puppetlabs.com
forge.puppetlabs.com is an alias for forge-web-fr.puppetlabs.com.
forge-web-fr.puppetlabs.com has address 18.104.22.168
Too bad when your puppet master is IPv6 only and you want to install or upgrade
I just filed a (Bug).
$ git clone https://github.com/.....
error: Failed to connect to 22.214.171.124: Network is unreachable while accessing https://github.com/.....
fatal: HTTP request failed
Which is correct. My host has no vintage IP address.
A friend is just being “spamed” with IPv6 training offers. Taking a closer look a the training company domain I’m wondering why I would by training (“for a successful IPv6 migration”) or support from a company where the main domain has no AAAA records for web, mail and DNS?
According to sixy.ch this blog is using IPv6 for 2230 days!
