local name resolution

RouterOS Beginner Basics
1

Hi

I’m a newbie with the routerOS software.

I’d like to have a local nameserver but I do not know where in the menu to activate.


I’m getting following information if i’m doing a local name request:

C:>nslookup 192.168.88.100
Server: router
Address: 192.168.88.1

*** 192.168.88.100 wurde von router nicht gefunden: Non-existent domain.


Internet Name server is working fine !

C:>nslookup www.google.de
Server: router
Address: 192.168.88.1

Nicht autorisierende Antwort:
Name: www.google.de
Addresses: 2a00:1450:4002:802::101f
173.194.35.55
173.194.35.63
173.194.35.56



Does anybody know how to fix that problem in the webinterface (or winbox) ?

Thanks

You can only add static ip address on
ip / dns / static

like mypc.local 192.168.88.100

thanks but that doesn’t solve my issue …

i’m not able to ping with name :frowning:



C:>nslookup 192.168.88.110
Server: router
Address: 192.168.88.1

Name: computer1
Address: 192.168.88.110


C:>nslookup computer1
Server: router
Address: 192.168.88.1

Non-authoritative answer:
Name: dreambox
Address: 192.168.88.110


C:>ping computer1
Ping request could not find host computer1. Please check the name and try again.

This problem has to be solved in your Windows DNS client. Ping, as well as most other Windows software, uses its various methods of name resolution (dns, wins, Netbios) and cache. Nslookup bypasses it, and simply interprets the response of one chosen DNS server.

To resolve the problem, go to your network adapter → TCP/IP → Advanced - DNS → Append these suffixes… And enter “.” for no suffix as the only entry in the list. Alternatively, you can have a domain zone such as “.local” as the suffix on all your hosts, and then simply enter dreambox.local in Mikrotik DNS.

When I was on Windows XP, I also had to completely uninstall IPv6, to get local name working. Because IPv6 added some IPv6 DNS servers, which bypassed the chosen local DNS server on Mikrotik.

Thanks that helpded a little bit.

Before on my Fritzbox router I didn’t need to change anything on my local computers …

I have a windows 8 computer and there i have to activate following in the network settings:

“use DNS-suffix of this connection in DNS registration”


But what can I do that also DHCP requested IP’s are also registered on mikrotik DNS ?

Thanks

On my computer, ping requires a FQDN. nslookup doesn’t.

Change computer1 to computer1.com and it should work.

after a reboot i've got the same problem as before :frowning:

Any help will be appreciated.

Thanks

nslookup 192.168.88.100
Server: router
Address: 192.168.88.1

Name: computer1
Address: 192.168.88.100

nslookup computer1
Server: mikrotik_rtr
Address: 192.168.88.1

*** mikrotik_rtr can't find computer1: Non-existent domain

nslookup computer1.kneuzgi.local
Server: router
Address: 192.168.88.1

*** router can't find computer1.kneuzgi.local: Non-existent domain


on the router I can see following:

[admin@Kneuzgi_MikroTik] /ip dns> export

mar/21/2014 13:43:31 by RouterOS 6.10

software id = 3G1U-3LR6

/ip dns
set allow-remote-requests=yes
/ip dns static
add address=192.168.88.1 name=router
add address=192.168.88.1 name=mikrotik_rtr
add address=192.168.88.100 name=computer1
add address=192.168.88.101 name=computer2
add address=192.168.88.102 name=computer3

Mine still works. What did you reboot? The router or the computer? I rebooted the router and the domains in “/ip dns static” still resolve ok.

I would start with using Winbox / Tools / Packet Sniffer configured to filter destination port 53 to see if DNS requests are made, to what destination, and also what is the content of the packets (if the names contain any suffix). Before every repeated lookup with ping, I’d use ipconfig /flushdns . If DNS requests are not made, Windows has to be convinced to do so, or if there is a suffix, that has to be appended to the static entries (or added as duplicates).

See if you have only one DNS server configured in Windows (the mikrotik), especially if you have any funny looking IPv6 “servers”, because sometimes Windows will query those secondary servers for local names, which obviously fails.

They get removed if IPv6 is uninstalled, which restored my ability to look up local, unqualified names. Maybe there is a way to remove them in console without removing IPv6 support.

after adding computer.local to dns and rebooting it’s working ..

Hi, I had same problem as you described. I simply solved it by adding an WAN interface to src-nat (see picture). My Windows Home Server apps in tray (dependant on local DNS) started working immediately. :slight_smile:

PS: IPv6 is disabled on all computers and server.
