IP Address Management Survey of Esnet sites – December 2011 Prepared by: LesCottrellSLAC, ESCC meeting Clemson University February 3rd 2011
Survey • 18 Labs responded in 3 days: including SLAC, ORNL, ANL, ORISE (ORAU), LBL (NERSC), LLNL, SNLL, JLAB, SRS, BNL, GA, PPPL, FNAL, ESnet, INL, PNNL and LANL. • Responses mainly from network folk (>80%). • Networks with from 100-1,000 (7%) IP addresses to between 10,000-100,000 (~47%) IP addresses. • Half of the sites have 100-500 subnets. • IPv4 networks with 1,000-10,000 end hosts (90%), 10,000-100,000 end hosts (10%)
Results • 47% having 1-100 Wireless Access Ports, and 47% with 100 - 1,000 WAPs • with most sites supporting DNSSEC, dynamic DNS, Active Directory and BIND as the DNS services • 8 sites have VoIP services
Why an IPAM • The most important reason for the move to an IPAM system was ease of use better management of the IP space. • Delegation of modifying hostnames and IP addresses varied across sites from 1-5 to >100 people with a mode of 10-20 people. • For about 2/3rd of the responders their PAM systems could delegate authority/control of the IP address space • IPv6 support was mentioned 6 out of 11 times as on the wish list.
Usage • 40% had partial support for asset management and 13% had extensive asset management support • IPAMs were integrated with enterprise databases such as personnel (33%), assets (47%), network monitoring (40%), security incident tracking (40%) and the help desk (13%) • about 2/3rd of the responders’ IPAM systems could delegate authority/control of the IP address space
IPv6 • Most sites use DHCP for most end user work- stations and laptops • 3 sites have no IPv6 addresses, 6 have 1-100, and 10 have 1,000-10,000 IPv6 addresses • 3 sites manage IPv6 with their IPAM
Products • ~50% of the sites use an in-house developed IPAM; 27% use a commercial product; 13% open source product. • the only IPAM application quoted more than once was Infoblox (2 times)
Support • Over 50% of the IPAM systems had been first installed in the last 5 years. • Initial installation took over 0.5 year in > 50% of the cases. • One site has > 2 FTEs required for support 33% have 1-2 FTES and 55% have <=0.5 FTEs
