Analysis

Hierarchy

The host names titanic.srcf.net, flame.srcf.net, lists.srcf.net, news.srcf.net and pip-webservices.srcf.net — among a few others — fall under the parent domain srcf.net.

IP Addresses

srcf.net points to the IP addresses 131.111.179.82 and 2001:630:212:700:2::1

fergalcotter.com, sjcjcr.com, clinsoc.co.uk and two other host names share IP numbers with srcf.net.

Name Servers

The authoritative name servers for srcf.net are ns0.lt0.uk, auth.ns.srcf.net, ns0.malc.org.uk and ns1.malc.org.uk.

srcf.net shares at least some of its name servers with other domains, for example malc.org.uk, srcf.co.uk, srcf.ucam.org and lt0.uk.

These name servers tend to co-occur with auth0.dns.cam.ac.uk, auth1.dns.cam.ac.uk, master.ns.chiark.greenend.org.uk and 4 other name servers in the same DNS delegations.

Four hostnames, each resolving to a pair of IP addresses: ns0.lt0.uk directs to 46.101.9.186 and 2a03:b0c0:1:d0::b0d:100d; auth.ns.srcf.net directs to 131.111.179.79 and 2001:630:212:700:8::1; ns0.malc.org.uk directs to 128.232.113.4 and 2a05:b400:110:1106::d:90; ns1.malc.org.uk directs to 185.45.112.101 and 2a02:e00:fff0:62::2.

Mail Servers

Mail for srcf.net is handled by two mail servers — olympic.srcf.net and titanic.srcf.net.

The mail server configuration of srcf.net is identical to that of other domains — srcf.ucam.org being one example.

Each of the two host names carries two IP addresses: olympic.srcf.net points to 128.232.113.66 and 2a05:b400:110:1198:70a9:f3ff:fe42:5ff8, and titanic.srcf.net points to 131.111.179.104 and 2a05:b400:10c:0:5031:e6ff:fe98:e808.
