Parent Status Message
NS Records at Parent Servers info We have successfully fetched domain's NS records from parent name server (g.gtld-servers.net.).
Domain NS records:
  • ns.nexylan.net. TTL=172800 [88.190.22.99] [NO GLUE6]
  • nx1219.nexylan.net. TTL=172800 [178.170.108.19] [NO GLUE6]
Missing Glue pass OK. Parent name servers are offering glue for domain's name servers. We received name servers list and it's IP addresses from parent name server (g.gtld-servers.net.).
Name Servers Have A Records pass OK. Found A records for all name servers.
  • France ns.nexylan.net. → 88.190.22.99
  • France nx1219.nexylan.net. → 178.170.108.19
To reach your name servers via IPv4 an A record is needed for each name server.
Name Servers Have AAAA Records notice NOTICE: While reading domain NS records at parent name servers, we found name servers without AAAA records.
  • ns.nexylan.net. → ?
  • nx1219.nexylan.net. → ?
To reach your name servers via IPv6 an AAAA record is needed for each name server.
NS Status Message
NS Records info Your name servers returned 2 NS records:
  • ns.nexylan.net. TTL=86400 [NO GLUE4] [NO GLUE6]
  • nx1219.nexylan.net. TTL=86400 [NO GLUE4] [NO GLUE6]
All Name Servers Responded fail FAIL: While quering domain's records, some of your name servers didn't responded. Name servers which didn't responded:
  • udp4:88.190.22.99
Glue Check pass OK. No differences found. The glue provided by the parent name servers has to match the data provided by the authoritative name servers.
Allow Recursive Queries pass OK. Domain name servers are not allowing recursive queries. On all name servers which acts as caching name servers recursive queries should be restricted to local networks. Having open DNS servers can lead to abuses such as cache poisoning and DOS (denial of service) attacks. Cache poisoning attacks allows under certain conditions to redirect legitimate web traffic, email and other traffic to malicious hosts compromising security.
Check Name Servers Count pass OK. Domain has 2 name servers. Recommended number, between 2 and 7 name servers (RFC 2182 recommends to have at least 3 authoritative name servers for domains).
Identical NS Records fail FAIL: We found different NS records on your name servers:
  • udp4:178.170.108.19: [ns.nexylan.net. nx1219.nexylan.net.]
  • udp4:88.190.22.99: []
Each name server should return identical NS records.
Check for Lame Name servers warn WARNING: We found name servers which are not authoritative for your domain. Lame name servers:
  • udp4:88.190.22.99
All of your name server should be configured either as master or slave for your domain, if a NS records points to a name server that does not answer authoritatively, name server is called lame name server.
Check All IPs are Public pass OK. No private IPs found. Name servers using private IPs can't be reached from the Internet causing DNS delays.
Name Servers Have A Records pass OK. Found A records for each name servers.
  • France ns.nexylan.net. → 88.190.22.99
  • France nx1219.nexylan.net. → 178.170.108.19
To reach your name servers via IPv4 an A record is needed for each name server.
Name Servers Have AAAA Records notice NOTICE: We found name servers without AAAA records.
  • ns.nexylan.net. → ?
  • nx1219.nexylan.net. → ?
To reach your name servers via IPv6 an AAAA record is needed for each name server.
Name Servers Have Valid Names pass OK. All names are valid. Name server name should be a valid host name, no partial name or IP address.
Check for Stealth Name Servers pass OK. No stealth name servers found. All name servers returned by domain name servers should be listed at parent servers.
Check for Missing Name Servers pass OK. No missing name servers found. All name servers returned by the parent name servers should have an NS record at your name servers.
No CNAME in NS Records pass OK. No CNAMEs found in NS records. RFC 2181, section 10.3 says that host name must map directly to one or more address record (A or AAAA) and must not point to any CNAME records. RFC 1034, section 3.6.2 says if a name appears in the right-hand side of RR (Resource Record) it should not appear in the left-hand name of CNAME RR, thus CNAME records should not be used with NS and MX records. Despite this restrictions, there are many working configuration using CNAME with NS and MX records.
Allow TCP connections pass OK. All name servers are allowing TCP connections. When response to a DNS query exceeds 512 bytes, TCP is negotiated and used, all name servers should allow TCP connections (port 53).
Name Servers Distributed on Multiple Networks pass OK. Name servers are dispersed on 2 different C class networks:
  • 178.170.108.0/24:
    • nx1219.nexylan.net.
  • 88.190.22.0/24:
    • ns.nexylan.net.
Name servers should be dispersed (topologically and geographically) across the Internet to avoid risk of single point of failure (RFC 2182).
Name Servers Distributed on Multiple ASNs skip The ASN information is not available at this moment, retry again in a few minutes.
Name Servers Versions warn WARNING: Name servers software versions are exposed:
  • 178.170.108.19: "9.9.4-P2"
  • 88.190.22.99: "Served by POWERDNS 3.1 $Id: packethandler.cc 2579 2012-04-26 11:28:04Z peter $"
Exposing name server's versions may be risky, when a new vulnerability is found your name servers may be automatically exploited by script kiddies until you patch the system. Learn how to hide version.
SOA Status Message
Check SOA Record info Domain SOA Record:
  • Primary nameserver: nx1219.nexylan.net.
  • Hostmaster (e-mail): root.nx1219.nexylan.net.
  • Serial: 2013092801
  • Refresh: 28800
  • Retry: 14400
  • Expire: 604800
  • Minimum TTL: 86400
Name Servers Agreement on Serial Number warn WARNING: We found different serial numbers on your name servers, it's OK if you had modified your zone recently.
  • 178.170.108.19: 2013092801
  • 88.190.22.99: 0
Having different serials on your name servers may show inconsistencies between name servers configuration (multiple masters), or communication errors (ACL and firewall issues).
SOA Number Format pass OK. Serial number format OK [2013092801]. Your serial number is following general convention for serial number YYYYMMDDnn, where YYYY is four-digit year number, MM is the month, DD is the day and nn is the sequence number in case zone file is updated more than once per day.
SOA Mname pass OK. Primary name server is nx1219.nexylan.net. and is listed at the parent name servers. The MNAME field defines the Primary Master name server for the zone, this name server should be found in your NS records.
SOA Rname pass OK. Contact email for DNS problems is root@nx1219.nexylan.net. (root.nx1219.nexylan.net.). RNAME field defines an administrative email for your zone. RFC2142 recommends using hostmaster e-mail for this purpose, but any valid e-mail address can be used.
SOA Refresh pass OK. Refresh interval is 28800. Recommended values [1200 .. 43200] (20 min ... 12 hours). Refresh field from SOA record determines how quickly zone changes are propagated from master to slave.
SOA Retry warn WARNING: Retry interval is 14400. Recommended values [120 .. 7200] (2 minutes .. 2 hours). Retry field from SOA record defines how often slave should retry contacting master if connection to master failed during refresh.
SOA Expire pass OK. Expire interval is 604800. Recommended values [604800 .. 1209600] (1 week ... 2 weeks). Expiry defines zone expiration time in seconds after which slave must re-validate zone file, if contacting master fails then slave will stop responding to any queries.
SOA Minimum TTL pass OK. Minimum TTL value is 86400. Recommended values [3600 .. 86400] (1 hour ... 1 day). Minimum TTL was redefined in RFC 2308, now it defines the period of time used by slaves to cache negative responses.
