Strange IP addresses. Need clarification
Posted: Thu May 14, 2015 8:09 pm
I'm not really TCP/IP savvy, just know enought o be dangerous. With consumer routers I have no issues whatsoever, but with Mikrotik I'm getting exposed to "too much information" and I'm getting curious what it is!
I set router using "Quick Set". I have static IP from provider.
Data from Provider:
StaticIP: x.x.x.130
Gateway: x.x.x.134
Mask: 255.255.255.248
1. What is "ARP List"? It shows 2. Why are they shown and what do I do with it? Do I understand it's devices from below?
x.x.x.129 (this is address of my other/old router)
x.x.x.134 (this is address of provider's box/modem)
2. Under "Addresses" I have one (interface1-gateway) x.x.x.130/29 but there is field "Network" and it's populated with x.x.x.128. Where this .128 came from? I did not enter it. It's not on any of my specs. System auto-populated it and I'm not sure what it means.
3. This one is completely weird. I use L2TP/IPSec to connect from my computer. When I establish connection I see new entry in "Address List"
Address: 192.168.89.1 <= This IP or even .89 is not known to me. I have no clue where it comes from.
Network: 192.168.33.207 <= This IP is from vpn pool, and this is address given to client. But on client side (Windows) address above 192.168.89.1 listed as DNS Server (Along with 8.8.8.8 which is my first DNS server on MikroTik side)
Lot of information, but I really like to learn what it means and where it comes from
