IpIsLocalChecker may throw about nowin

[MeirionHughes]

I have the same with a (very) minimal build for embedded machine:

Unhandled Exception:
System.Net.Sockets.SocketException: Could not resolve host 'microzed-zynq7'
  at System.Net.Dns.Error_11001 (System.String hostName) [0x00000] in <filename unknown>:0
  at System.Net.Dns.GetHostByName (System.String hostName) [0x00000] in <filename unknown>:0

• Throws if hostname not known to DNS
• Throws is DNS unreachable

Ouch I nearly forgot about this one. I saw that you fork it. So do you work on fix on your own?

[dorvan]

also this initialization cause random problem about binding allocation. and application become unstable
..on linux...

[MeirionHughes]

yeah I just tested this; simply catching the Socket Exception does the trick and the manual endpoint will kick in.

Its not great but it fixed the issue on my embedded system. Not sure if you want to handle without resorting to try..catch...

[Bobris]

Looks ok for me. Merged.

[MeirionHughes]

Do you know when this can be included in a nuget release/pre-release?

[Bobris]

I will do it in next 14 hours.
