Historic datasets (from 2014 onwards) for the .nl TLD. Datasets are available in JSON format.
Datasets cover information about:
Historical DNS database. Access can be requested for academic use.
Activly queries many DNS records, e.g., .com zone.
It can contain information not in DNSDB, if the information was never seen by a resolver.
It does not contain all informatin, as some domains may be unknown to the project and thus cannot be crawled.
It uses popular zones, domain lists (e.g., Alexa, blacklists) and other domain feeds.
They normally maintain a rolling 14-day window.
Copy files (for date 2017-10-05) (ddos@gladbeck):
sftp -B1024000 -C -rp "activedns@kokino.gtisc.gatech.edu:active-dns/20171005/" .
The data is encocded in AVRO format, which can also be parsed as JSONL. Python has a AVRO library. AVRO schema:
{
"namespace": "astrolavos.avro",
"type": "record",
"name": "ActiveDns",
"fields": [
{"name": "date", "type": "string"},
{"name": "qname", "type": "string"},
{"name": "qtype", "type": "int"},
{"name": "rdata", "type": ["string", "null"]},
{"name": "ttl", "type": ["int", "null"]},
{"name": "authority_ips", "type": "string"},
{"name": "count", "type": "long"},
{"name": "hours", "type": "int"},
{"name": "source", "type": "string"},
{"name": "sensor", "type": "string"}
]
}
Some more information about some fields that are unique to that schema. The IPs in Authority IP are the collection of the authority name server IPs that replied to our query. We gather all the IPs that gave us the same answer for an entire day and concatenate them on the same field, mostly in order to reduce the number of records that we have to keep. The only field that might be slightly confusing, is the "hours" field. This is a 24bit integer that encodes the time of day we saw this RR for date date (for example, 000000000000000001000010 = 18:00 and 23:00). Another important thing to keep in mind, is NXDOMAINs. A resolved QNAME does not exist when both the rdata and ttl fields are equal to null. If rdata exists but ttl is null then the record was part of the glue of the DNS packet and not in the answer section.
BGPlay shows a graph of the observed BGP routes. It allows to replay historical BGP announcements and displays route changes.

It also provides a nice API to query the location. It provides a breakdown on where the results stem from and how much they contribute to the overall result.
This is an improvement on the traditional traceroute program. It is able to detect multiple distinct routes and display them accordingly. The classical traceroute would produce weird results on changing network routes.
Another similar program is Dublin traceroute.

PEERING is an environment where researchers and educators can play with BGP announcements in a real but sandboxed environment.
Description from the website:
The long-term goal of the PEERING system is to enable on-demand, safe, and controlled access to the Internet routing ecosystem for researchers and educators:
Contains information for some networks about peering information. This includes peering partnes, transfer speeds, peering requirements and similar.
The public suffix list gives a way to easily determine the effective second level domain, i.e., the domain which a domain owner registered and which can be under different owners.

RIPE operates a set of probes, which can be used to send pings or similar measurements. The probes are mainly placed in Europe but some are also in other continents.
All the collected measurements can be found in the RIPE Atlas Daily Archives. The blog post gives some more details.
Different information regarding reachability and connectiveness of ASs.
The Route Origin Validation (ROV) Deployment Monitor measures how many AS have deployed ROV. It uses PEERING for BGP annoucements and uses BGP monitors to see in which ASs the wrong announcements are filtered. A blogpost at APNIC describes it in more detail.
These websites allow you to browser the valid RPKI announcements. They show which address ranges are covered by RPKI and who the issuing authority is.
